Random Wire w/ 9:1 unun Part 2
Вставка
- Опубліковано 22 сер 2024
- So we want to keep playing and honing this random wire, to find the length that works for 80-10 meter.
So I’ll be adding length.
The wire is currently at 39 Feet.
I forgot to mention I was able to tune this for 6 meter FM. Had a QSO with a operator on my local 6 m repeater. So that was fun.
But with help from friends and our community. I think I’m going to try the 71 foot wire next. Stay tuned for part 3.

Thanks mike very interesting and educational
Glad you enjoyed it
Awsome video Mike
Just a suggestion, maybe you could make a video showing how to properly do an RF exposure evaluation including how to document it and what form to use for FCC compliance? Just a suggestion, might be useful to those that don’t even know what I’m referring to. Thanks!

I knew out of my 600 videos that I had one for this. hope this helps you out. 73
@@mikecricket113 Thank you sir.
Don't forget to add a 1:1 UNUN so you don't bring common mode current into the shack. I just bought a couple of them for a new 9:1 balun I'm making for a random wire antenna for POTA. I'm going to drop a video of how to water proof the LDG enclosure so it can be left outside.
It’s in line behind the LDG shown in the video. Using the MFJ 915
Look forward to your video on weather proofing.
I took the same 91 ballon got the LBG joke hook them together with short a259 coupler and hooked it up to my rain gutter and it works beautifully I've talked to Italy and all over the the place my building runs north and south soap for predominantly I have South a little bit of North and a lot of West
I am so happy to hear this news!!
I,m going to try and find a local CB club in my area. Get my antenna calabrated properly 📻👍
Good luck!
I just got one of these today,I think i am missing something,I cut it for 12 meters 24.940 3.7 swr and then I checked 20 meters 14.240 and the swr was 1.02 I did the 468÷2 for 12 meters.
Any ideas mike?
Nine to one is for random length of wire. It’s not really random. But the lengths are not half wave at all.
Read this link I am providing for you. Near the middle look for the numbers in GREEN. Use one of those lengths for an end fed.

I used 71 foot of wire. Got me on 160-10 meter. But you chose what’s best for you.
@@mikecricket113 oh ok I read it that makes sense now...thanks
Where did you get your splitter? I'm wondering if you used the eavsetrough I may try connecting to the metal roofing and see if it works.
Thanks for sharing
I am confused about the splitter you’re asking about?
@@mikecricket113 it's the red box attached to the wire
@@mikecricket113 I'm sorry its the 9-1 balun
Oh.. DX engineering
Have you tried it with a counterpoise, and what where your results?

Yes about 17feet. Got me on 160 meter
@@mikecricket113 Great! And may I ask you how long your end-fed wire for 160m (about 135 feet?)
