- Wilson Little Wil CB Antenna Disassemble and troubleshoot Bad SWR.
Lets look and see what this antenna looks like inside. This is a great antenna for a stock CB in a temporary type installation. Dont push more than 1oo watts through this antenna and it will last for a long time. Put a little silicone around the coax as it passes through the base.
BTW...This antenna is very easy to tune, and has decent bandwidth (for a mag mount )

Thanks for posting the vid. I wasn't sure how to tear it down. My set screw rusted out on it. Now I have to buy a repair kit. But it's a decent antenna for what I use.
I just purchased one of these. thanks for the information will seal it around the coax
Tuned easily and works well. Yes you are right. I am saying about my Stryker SR-A10 CB Antenna. Quality materials, excellent whip, difficult to cut with your standard wire cutters FYI. The magnet is super strong, all around terrific product. Couldn't be happier with mine. I got an SWR reading of 1.2 on 19 and 11 and somewhere around 2.2 on channel 40 and 1. Installed on top of the roof in the center and have the cable going through the rear door and on to my CB handheld Midland that plugs into the cig lighter. There's a little feedback but I think that's normal. Great product.
I also have the midland handheld. What is the best ch with out cutting the antenna?
My little will was giving me high swr on and a bit of trimming on the bottom of the antenna gave me almost perfectly even SWR readings on ch 1 and ch 40 right below 2.
Thanks for the explanation. Well crap I ordered the lil wil because it was shorter than the bigger wilson's. I planned on running a little heat on it because it said 300w rating. Thanks for the video it saved me from burning it up. I guess I'll leave it bearfoot on my truck.
I'm having great difficulty getting a good SWR on a new Little Wil. Now tempted to strip it down to as if there's an internal fault.
@BB23 The 1000-5000 are a direct hook up at the mag mount ,, but the coil is matched with a capacitor
I think they're rated for 300w. I have one on my F150 hooked up to a 959. But like you said... "rated" for 300w doesn't mean it will actually handle it. Thanks for the tear-down and explanation video! I may start looking into other magnet base antennas. I'm definitely not a fan of K40's due to bad experiences. The best I've found are the older "Moon Raker" antennas. They're hard to find around here though. Thanks again!
I've finally stopped w/ a co-phased pair for background noise cancelling, proper is twin 75 ohm coax soldered to the assembly. Thunder Bolt 200 does great. 75% efficiency means I'm splitting 150 watts in 2, but I can talk from the city to 41 miles back to the house each night like it's nothing (or right next door as it were).I'm keeping this cause I park in parking garage at work and over all height of stingers on road picks up great AND is still safe in 12 flites a day going to and coming from work.
Sounds great, I like the "thinking outside the box" setup. Cheers.
May break today but be sending 225 through one for several years. Lil will holding up fine.
Just got one of these for my wife’s car. Uniden handheld to the Lil Will. SWR was way high on ch 40. That’s with the whip all the way down. Had to cut a 1/4” at a time to get 40 and 1 to about 1.3 swr. After that it was awesome! Had a short skip conversation from SoCal to Mobile Alabama. Conditions were super right!! Didn’t last long though.
I've had to do same, how much did you eventually cut off?
sly200sx Ended up about an inch. Cut small increments and you should be good. If too low you can always raise it up and lock it with the screw.
rallypoint1 jeez. I had to cut off 3.5 inch 😂😂😂😂😂
sly200sx well...if that’s what it took. LOL where did you place the antenna? Mine was on the roof so there is a lot of metal for ground. Maybe on the trunk is less metal and needing a ground strap from trunk to body.
rallypoint1 it’s the roof of a new A class. Maybe lots of alu
The lil wil is the only wilson mag mount that uses that matching system. The 1000-5000 are a direct hook up .
73s......BB23
Moisture will skyrocket the SWR and also burn stuff up with shorts. Dry the thing off once in awhile. I ran a hot rodded Cobra 25 LTD, one watt swinging 20, into a White Tornado 225, through a Little Wil for several years with absolutely no problems. It had real good ears and I talked to whoever I could hear,skipped all the time . Great for lil amps like a 225.
I agree !!!
I replaced my Wilson antenna with this Stryker SR-5K Antenna after I lost it on the highway. It tuned well and I don't notice a difference from the Wilson, except the price!
I like the Stryker 5K WAYYY Better. Both TX and RX.
It is the exact same antenna as the Wilson 5000. Same Box even.
I sell them for $60 on our web site and in my store. They are the best bang for da buck. Thanks for your comment BB23
+breakerbroke23 kindly upload review for sr-5k cb antenna. Your videos are quite informative. Great communication skills.
Price Tag is affordable. I bought it on $63.
yea, the more I look at that burnt component me thinks it WAS a resistor.
Wilson rates the lil wil at 300 watts. Any way the coil will take it the matching circuit wont. Thanks for your comment.....BB23
So if just a 100watts fry the capacitor. Would that be a weakness in the larger Wilson's? Or do they use more durable capacitor's?
I believe the capacitor is a 180pf at 1kv.
Yeah Just googled it and is states it will hold 300 watts. in many places. I just wonder if you got a bad one.. N7BOW Pete
They are sealed, look at the silicone on the treads where the whip screws on in your left hand. It’s white.
There are two capacitors in my antenna, one is 120pf 1kv and the other has no indication, do you know the value of the other one ???
I was working on replacing the (door jam crimped) coax on mine yesterday, I measured the capacitor as 7.9 pf on mine with my LCR meter while it was out of circuit, (The markings on it are; 1 KV 180K B ) (180K comes out as 18 pf in value so my capacitor is definitely out of spec.) And I remembered seeing your video and came back to comment.
Yours visibly appears to have an additional small molded inductor in parallel with a blue capacitor in the matching network. And the video seems to suggest there was a second one after this, that had deteriorated or the blue one it self had partially deteriorated. But I may be mistaken in this from watching the video.
Mine (which was bought used but was working well, may be older, or previously repaired or modified before I got it.) only has the single 7.9 pf (as measured value) capacitor from the ground lug to the coax center connection point.
Can you give me any data on those parts your video seems to show on your unit ? Is there a smaller molded inductor in parallel and does it have a visible color code? Were there two capacitors in series in the network or just the one blue one the video seems to show?
I can easily take mine back apart and rebuild it as it once was with a new capacitor of correct value, and perhaps measure the coil inductance as well along the way as I do so..
My replacement RG8u coax @ 18 feet long has moved the 1:1 SWR a bit off from the original RG-58 15 foot length anyway. I was planning to reset the SWR later today for the same mounting point it had occupied.
But reviewing your video again this morning gave me a few questions to think about.
I can't give any information as we have thrown out the antenna and replaced it with a stryker 5k mag mount,
going from the lil will to the stryker is like night and day. You could get a hold of tech support at wilson and ask them, but as with most company's today, I highly doubt you will get any info. I hope i am wrong. Good luck and please report any findings, Im sure there are people that could use your input...BB23
The cap on mine is marked 131 1kv. The inductor is unmarked, but looks like 12 turns on 14" air core.
I have a Wilson lil wil and I am running mind off a Cobra 29 Ltd classic Peak and super tune and I am having the same problems as seen on the video and I literally just bought it 2 weeks ago and I think my Cobra 29 frighted one minute I have good SWR and the next minute my SWR meter will go haywire for no reason and as far as reception it is very poor and this is the second one that I went through
Wonder what frequency it resonates straight to the big coil? Looks nice and beefy. Looks like a bandpass filter bunned out and may not be needed.
hats the matchable bandwidth without cutting the antenna? Would like to use it for 40m - 10m
you would need a HUGE whip for 40m with this base as the coil is not very long.
I have one I ran with shoes on about 300 watts I think the problem was the moisture in it
Hit the lil wil with a 2x2290 and it did the same thing ;( Hope to find the specs on that component. smells bad too
spec says 300W, i suspect there was another issue, maybe moisture
Yes ... on the paper ... yes
Hello, If I was to get a new mag mount, I would use the wilson 1000. Its a good antenna with a great magnetic base. Plus if you decide to roof mount it the proper way, just get the roof mount kit. I must confess .... I do not like mag mounts. I use a 5000 roof mount on our burban, its been on for 11yrs with NO issues. Thanks for your comment.............BB23
I hate magnet mounts too
Like base load CB antennas, they have power limits. The spec sheet put out by Wilson says "300 watts" maximum amount of power. My question to Wilson would, are saying 300 watts maximum power 300 watts peak envelope power or dead carrier? Personally, I'm betting they are measuring peak envelope power. A stainless steel quarter wave whip is way to go when doing the " more than 4 watts thing". but as we all know, not every situation permits this type of antenna.
Try reading the cap. That caps good it had a cold solder joint.
Mine does great on top of car 12-15 mile range with about 40 watt. Anytone at-6666. Cannot complain.
Ran 200 watts on mine little will and still going......
I'am Your Newest Subscriber Great Videos I got That LIL Will Antenna At The Fleamarket In Tampa Florida Funland Swap Shop For 5.00 I Hope Mine Works
Thanks for this video.
300 Watt max on these little wil antennas. There's no way a barefoot 200gtl fried it. Either it was faulty from the factory or there was "magically" more than 300w thrown at it. 😉😉
300 watt max. I got the same antenna on my F150
Were you ever able to locate the disc capacitor value and do you know where to find a replacement for the weather seal on the bottom? That looks like mylar but not sure. Thanks for the great piece.
No I was not, and the customer just bought a better antenna. Wilson 1000
capacitor is 121j 1kv 1000pf ceramic disc capacitor, air core inductor between the two capacitors is 12turns
I own this antenna on my daily driver car. However on my truck 102" all the way baby! Nothin beats a 108" whip (102 antenna + 4 inch spring + 2 inches or so of lug) oh btw.... I get a 1.1:1 on channel 1 and 1.2:1 on 40. That is on my Uniden Pro520XL tuned by Screwdriver at bells. swinging 30 watts pep.
that's because your running it properly with the spring and ball to get the proper length for your frequencies. Good job. wont matter what radio you run into it the antenna is resonant on the CB band at that length
Wow I made this post 3 years ago. Well since then I have gotten my Amateur Radio License and have 1100 foot of loop antenna, balanced line tuner, 1500 watt Al-800H amplifier, SteppIR BigIR Vertical Antenna with 60x65' radials, DX Engineering Active Receive Verticals, Flex Software Defined Radio, and a host of other tools and antennas. CB got me into HAM radio and HAM radio is about superior to CB in every way. Not saying superior in people but the ability to go where ever from 1.8mhz all the way to multi-ghz frequencies and everywhere in between. I don't use the 108" whip anymore. I use a Scorpion SA680 Screwdriver Antenna and I use an ICOM IC-7000 while mobile. I still have my UNiden Pro520XL tuned by Screwdriver in Florida and the little thing swings 27 watts which is awesome. But I find CB radio to be highly undesirable these days due to the trash talking, every other word is the F word, kind of Trucker language on every frequency it seems. That and Skip is down very badly right now and will be so for years to come on 11 meters. But DX is good on other bands. Get your HAM license and come out of the Dark Side to the other Dark side haha. Its good over here.
I failed to put this in my last post I am new when it comes to the Cb I am Not too for sure on exactly how much power my Cobra 29 Ltd Cobra is putting out but I bet it is not putting out a hundred watt and it fried my antenna I will never get another little will again
Usually 5 watts a cobra 29lx
Thanks for this video. My SWR is in the RED channel 1 & 40 TX and REV! Should I start cutting the Whip incrementally??
Something sounds off... Make sure your coax is not cut into or kinked. Make sure you have in on a large enough piece of metal. It the antenna used? possibly the first owner blew out the innards.
I would also measure the whip and see if it was already cut ( maybe way to short)
These antennas will usually tune quite easy and as long as the SWR is in the 1.5 area should work fine. But most definitely sounds like your may have an internal issue. IMO
@@breakerbroke23 I just opened the Little Willie mag mount I bought a few years ago and on the cardboard instructions it talks about cutting in increments of eighth of an inch you know as per instruction etc etc etc the CB is the president brand new swbr is brand new jumper cable brand new the Magnet mount is on the wooden desktop does it need to be on a piece of metal thanks in advance..
@@breakerbroke23 put it on metal and a big difference!!!
DOH!
NICE!!! I'm glad you figured it out. You are now an official radio geek:)
Welcome....
@@breakerbroke23 gonna take my test for TECH next month.....I have 30 hrs. of study...LOL
This Hillbilly kinda slow....Hahahahahaha!
My Vanity Call Sign will be "M3PPS" ...when i graduate...:)
Give me your supposed to be toast,lol. Master tech.
Hi Dont see why you would need a matching network inside a magmount, why not get a normal magmount and put a DV 27 on it, short aerials are not that great anyway...Fred in uk.
Might as well get a wilson 500. It takes 2000k and is only 54 inches.
So, it would really help if you posted the value of the 2 components if you found them??
I tried and got no help from "tech support" So I just checked the Antenna, We put a wilson 1000 on the vehicle and got WAY better performance.
Cheers.
EDIT.... Chucked it.
Sirio 4000 hi power when you absolutly positivly need the best !
hmmm. i have the sirio.. its not all its hyped up to be imo
hey breakerbroke23 you know tram-browning antenna co. they are straight solder to coil and ground you can run a lot through these guys not wilson though and tram and browning is cheap and works well sir ive called tram and they say even there small 3inch mag can run whatever yo want through them LOL cool huh
Junk,use President or Sirio antennas or other high grade ones,people who skimp on the most important part of radio system! Great vid,thx
I just got my radio back from service and tried to use a lil wil and it pegged the swr meter. I pulled it apart and nothing looked burned. I just spend 500 dollars getting my Cobra 148 resto mod with lescom 10m board and didn't really want to take a chance with a shit antenna. I went ahead and ordered a new Wilson 1000.
From what I have read, just spend the extra money and get the 1000.
Mate you got a decent radio and shit antenna why risk your outputs. Buy a sirio 4000 much better than wilson 1000
@@mistermeanor968 Sirio has his problems too
The cap in series with the coil appears to be a 120pf @1KV
Thanks for the info........ BB23
On the one that was given to me, the caps were in perfect shape. It looked like someone tried to replace the coax and made a mess of it. Even in your video it looks like the original coax run is a little convoluted. (I think they do that so that nothing breaks if the coax happens to move a little bit.) I ended up running the coax a little differently and didn't bother covering the coil and caps. (the heat shrink would only hold in water anyway.) The SWR still dipped nicely and the antenna appears to be working just fine. Since my coax run was straighter than the original, I put a little bit of goop on the coax to prevent it from moving inside the assembled unit. The 2nd little coil does serve a purpose. The center bolt on the bottom of the coil is not attached to anything and serves as a ground post. It is there to bolt the assembly together. There is some good reading at the k0bg.com/match.html for anyone who wants to understand why this little coil is necessary.
Yeah that's not waterproof what good is it CB antenna it won't keep the water out well now I know what not to buy I want to get back in the game again but I'm not wanting to piss away some money either thanks for the heads up man
I bought mine to listen and talk to the truckers on the interstate. I dont need 2 or 300 watts.
Yep, nowadays when I road trip I have never needed more than the 3-4 watts my mobile puts out.
Did you ever find out what that little electrical component was? A capacitor or maybe diode? Its rating? I have the same problem.
No I did not, the customer bought a Wilson 5000 and was happy.... Somewhere down the comments a viewer identified the part and value.
There was no other component. The lead from the matching coil burned through. Replace the coil connection and all is well until you overdrive it again.
@@mztrclean I have a standard 4 watt CB. Hard to over drive an antenna with that.
@@pipedreams57 Same here. Just wondering.
@@breakerbroke23 "Somewhere down the comments a viewer identified the part and value." Where?
Solder those two back together. Cold solder joint happens often.
+breakerbroke23 I bought sr-a10 cb antenna. Great product, very close to 1:1 SWR on CB! This antenna will give you four times the range of a cheaper antenna. Pay a bit extra money and get this one. Thank you Stryker.
I have a couple of the 10s. They look mean as hell, but they are made in china. I will do a video on on of them soon. Thanks for watching. BB23
Most antennas (K40, Wilson etc etc) are manufactured in China. b/c they offer low manufacturing rates. I will try to upload its review soon.
Thank u .i bought it SR-A10 Cb antenna it fill full my needs.
I bought Wilson cb antenna but it Quit working a few weeks after we got it horrible antenna do not buy. The beast i recommend is Stryker antenna ***SR-A10*** Works great in all conditions with great SWR 1:1 loud and clear even on long distance.
The SRA10 and Stryker 5K mag mount is good as well. Thanks for watching
Sirio 4000 hi power !
Best mobile antenna ever made .
He ain't Talking a Damn Thing!! whats with these guy's
Made in America.
Had nothing to do with power it was moisture
