... I have about 16 radials going out to the front and back yard down the alley next to the garage. They are made out of 14 gauge stranded copperweld naked...
... I forgot to mention that I also installed light weight wire mesh hardware cloth measuring 4ft. by 15ft. under the antenna. This helps the ground plane...
... I really like this house mount as my home has a 18KV power line? running across the back of the backyard keeping me fron erecting a 43' without a guywire...
On 40 I go direct, on the other bands I get 1:1 swr using my MFJ tuner, with no unum or balun. Don, W4CBS [Non-text portions of this message have been removed]...
What is your SWR on the bands other than 40M without the tuner? If it's high you will have huge losses in your feedline. That's why the unun is needed. It...
Hi, First post. Does anyone have any experience with roof mounting a S31? Long, long ago, I had a HyGain 18AVT/WB on a 2nd floor, flat roof. I would really...
... Chas, so far the only thing the antenna has gotten into is my CO2 detector. Course all my antennas get into that one and my touch lamps. No problems with...
... I PLAN to roll out about 25' of plastic coated chicken wire and run it down the West easement of my yard except for an area sufficient to contact the ...
Try a Google on 4:1 unun and get info to build one Honest its not too hard!!! Something about building bits! Thanks Chris Baker B.A. Sunny Morecambe, the...
Well, last evening, we had another powerful cold front come through New Orleans with wind gusts between 60 and in some parts over open water, 90 Mph. I live...
Hi Group, We're adding the RU-4:1, a 200 watt 4:1 Unun to our Balun line (Ok, now Balun and Unun line). Since we've acquired S9Antennas, we've found that we...
Basically the 1:1 ensures that the coax does not radiate and RF does not get picked along the coax. Rule of thumb is that the 2 vertical lengths are 1/4 wave...
No problem just remember the 1:1 is a choke to isolate the feeder from the radiator. My old radio lecturer used to tell us that a aerial is really part of the...
The 31 is only $95 and LDG is supping an UNUN with it and a 4:1 coming later at no extra charge Clyde de AB4CC [Non-text portions of this message have...
Can a SG-239 be mounted at the bottom of the 43'Vert at the end of about 200' of LMR400? If so, will an UNUN be required between the AT and the bulkhead? or...
I just placed an order for the S9v43 from CheapHam today. Just crossing my fingers that it will arrive prior to Field Day. I'll probably receive the un-un...
If you have a remote tuner at the base, it is my understanding that you do not need an unun. ... [Non-text portions of this message have been removed]...
... THE tuner at the base is NOT going to stop rf traveling on the outside of the coax. that is what a choke coil, aka unun does do. of course, I could just ...
You probably are choosing the SG-239 for its power handling capacity over the SG-237. Another consideration is that the 237 is waterproof but the 239 is not....
I've had my S9 31 foot vertical for awhile. My original installation was with the antenna mounted on top of a 30 foot telescoping mast with four tuned...
I may have been the last person to purchase my S9 from the previous owner (cool huh!). And I will continue to purchase this antenna from LDG. It boggles my...
