TV ANTENNA TESTING WHICH IS BETTER
Вставка

- I load up the two tv antennas in the back of my truck and take the two tv antennas to a wide open field to test the two tv antenna whiskers to see which one has the best signal strength.

Danny S Hodges You mad the test wrong, that two antenna's hav two diffrent locations.......
,
I started watching one of your other antenna videos late last night and wouldn't you know I'm starting to see a bit of light in the sky! It's 6:48 in the am and I've turned a simple "How To" video into an endless marathon session! Thank you brother! I'm really enjoying all your content.
Thanks for the information. Keep doing what your doing. I'm thinking about building one myself the one I have is like the one you tested (360 TV Antenna) awhile back and it doesn't do the job. There some channels I can't get and some I loose when it rains, frustrating!!!
I have an idea for you fella. Since space is at a premium. How about using a coil design for the elements ???? Reason, since you can increase the length of a wire and keep the space a compact size. What do you think Danny ???
Great job bud , love ur videos
thank you sir
Hi Danny you probably already know the signal strength of an antenna is called db gain he claims his has more db gain. But to really maximize the gain of the antenna because it is tuned exactly to the frequency that the channel is on. Thanks for all the great videos. Keep em coming
Thank you Danny S Hodges for sharing this ideas of your... I made my own too...
on your Bowtie (new design) have you tried different wire lengths? Maybe you could use a longer length of wire for the Bowtie antenna to move your center frequency closer to the VHF low spectrum and test it. Just a thought.... Keep up the great work!
Hi Danny, I think what you're not testing is the impedance and proper antenna matching. You see, the X-shaped antenna is what is known as a "fanned" dipole (although many think they are an opened up bowtie. they are not), whereas the other one is a bowtie element, which is in reality a closed loop (which should have more gain, more bandwidth and less noise, however generally their impedance is higher). The dipole version, they naturally have a 75ohm impedance at a half wavelength, however the bowties may have a much higher impedance and may match much better if you add a simple 300 to 75 ohm balun. So if you get a chance, you may want to try using the whisker / fanned dipole with direct coax feed, but use a balun on the bowtie v ersion. The results may be fundamentally different.
Danny have you tried making bowtie dipole and whisker dipole antennas combo? like let's say you're making a 4 bay and 2 are bowtie and 2 are whisker, would that compensate and give you the best of both worlds? especially if you antenuated the weak frequencies on each set of dipoles ?
I want to see the sixteen ultimate antenna Danny. Maybe you could show us the video you have in mind ??? Thnaks
Danny, have you ever compared your ultimate antenna to a large yagi or log periodic style antenna for range?
inline bullet shaped RF antenuators are vailable for coaxial sold for 50 cents or less.
My suspicion is the closed bow tie is tuned" better to UHF and not so much on VHF HI, Probably the open bow tie interacts with refelctor to make a better VHF result...
I watched this again and I noticed that the bow tie type is good for UHF and the wisker type is good for VHF. So if you experiment and made a four bay bow tie type for UHF and put a wisker type on top for VHF separate from the bow tie with it's own separate transformer. I believe it would be one great antenna. What you think?
The bowtie looks to be just as long as the wiskers? If so adding the extra 2-3" puts the bowtie sweet spot in a different frequency.
You would be very interested in the AARL antenna book. I'm working on a homebrew 360 degree Tv antenna that works the same as a old starduster cb antenna. I have only tested it indoors so far but it is surprising the heck out of me!
UNIT 10 I have several old style and new style stardusters and I think the old ones are the best ground planes ever made (next to my design lol) the new ones are junk so I use the aluminum from the new ones to build my ground planes and throw the cheap plastic hub away. I keep the good aluminum hubs from old stardusters that people toss away or they sell them to me and I build new stardusters on the old design and keep them to sell. as of now I have quite a few 17 I think. I'm going to keep 7 and sell the other 10
did this antenna work good danny
Closed loop bowtie dimensions are wrong.
Bow tine length is supposed to be the same but the ends are bent together at 80 percent of the length to form the closed loop bowtie.
So for instance a bowtie with 10 inch tines would have the ends bent in at 8 inches.
The result would be an 8" wide by 4" high closed loop bow element.
A bowtie is essentially two dipoles rotated in opposite directions.
The closed loop comes from a space saving technique use with dipoles. The bent end dipole.
@Danny S Hodges how good do you think it would be if i just put A rabbit ear indoor antenna weatherproofed and install it outdoor on a pole? on ebay you can get them as low as $3.99 but i happen to have two of them . i just want to do 65 miles or more
Yo Danny! You mentioned the things not being perfectly aligned and stuff like that. I got one that I'm watching television with that getting about 15 channels but it's only nine feet off the ground and it's not really aimed at just kind of flung it that way in I think I'll get around 40 once I put it on the roof. But this thing is so bent up and these antennas work like through whatever.
cool antenna danny

nice,,like it
hey man, on that Bow Tie, cut it out like the Whisker ones you make but leave a 1/4 inch on both and put some Hard Tubing between them and maybe some Epoxy Glue to help hold them in place. That the way it will still keep them lined up.
Good Videos! peace...
Great idea s tructure without locking the tuning into UHF with completely tuned closed bow tie.
do you know what booster is better the RCA TVPRAMP1R or Winegard boost xt model lna-200, Or the Channel Master CM-7777HD
nice what you should try is add one bow tie to the top of your ultimate antenna I bet your be surprised
it is simple and perfect
tks
Danny why don't you take one of your cat whiskers the v portion make one of those 32 in Long and the other half of the Vleave it the way it is and do the same thing on the opposite side this will give you one low band VHF and then one UHF they both work you can leave the screen reflector like it is if you want or make it bigger and move it back it doesn't really make any difference but just try that and see what happens you may find you can pick up VHF with the UHF at the same time it's just a simple test but you can try it and see how it works
I've noticed there are some antennas wires that are bent in a circle and some that are just the v shape. have you tried to make one with the v shape and circle antennas together ?
I MIGHT TRY THAT
Now Danny, I know why you tried that closed end bow tie design. It's because it's less likely to stick through your arm! Man that video made me squirm, man that had to hurt!
lol
Danny I have a problem. I have been using a regular 8 bay ant and was able to get a pretty good signal on almost all of the local stations in the area. I decided to cut it down and use it to build your ultimate antenna and I built it exactly to your specifications and hooked it up to the same cable I used with the 8 bay and now I am only able to get 4 stations instead of the 29 stations that I was getting. I have triple checked every detail and no matter what I do I can't get any of the other stations that I was getting. the 4 stations that I am getting do have a good signal and stronger than the 8 bay was but I was getting 29 stations on the 8 bay with an average signal of around 55 on all of them. I only get 4 stations now on the ultimate with the signal and around 70 and I don't know what else to do cause I used my 8 bay to build the ultimate. I should have left my 8 bay alone. I am a dish network and directv installer and technician and very good at it but over the air TV is beyond me. but I can and do build some of the best CB antennas on the east coast but I can't build a TV antenna using someone else's proven design and make it work to save my life. what am I doing wrong Danny
you need to hit me on facebook.i will help you....ultimate is best antenna u can get,,something is wrong...people have made thousands...danny s hodges facebook
ULTIMATE REVISED..You need to watch this this is mine video on another channel....ua-cam.com/video/9mv9pnpNap0/v-deo.html
I have watched several of your videos and I could be wrong but I have not heard you mention grounding your antennas. This is a step that cannot be overlooked by someone attempting to diy on their own. Lightning can and will strike a antenna and grounding will prevent your television from exploding at the least as well as preventing your house from catching on fire. By the way there are Chinese companies that have copied your design. Walmart is now selling them on their website for between $60 and $100 depending on the brand and distributor.
My goodness copy? Are you kidding, that design has been around a long time in fact it was popular in the 50's right after uhf came out . I installed some 8 bay in the 80's and even the double bowtie parabolic antenna Channel Master had. but remember these are only uhf antennas we always add the vhf with them for all the channels around here .
@@debohannan4315 I know, I kid because he calls it His ultra design. ;)
what I can't believe how cheap they make the clear tv antenna and charge so much u can make it out of aluminum foil plates
right
