I sadly purchased the above antenna, hoping to be able to have a little
better reception/transmission than I currently have. My area is restricted,
with only a backyard (20'x50') available. There's a huge live oak situated
in the center and two feet from the fence which doesn't help with
deployment. Ground radials are not feasible.
The antenna as per spec provides a very low SWR across all bands without a
tuner. There are background noises from 160m to 20m at which point it goes
deaf and mute 17m to 6m. On the Monday night 10m net I can barely hear or
be heard by a HAM about 5 miles away.
So if any of you adventurous souls have a hankering to try something new as
soon as I've replaced it (very soon) it will be available to try out. Just
contact me.
Notes:
1. Recommended height is 35' and I have it at 20', manufacturer's email
(available) told me that even at 20' it should respond better.
2. Same email from the manufacturer indicated it uses the coax shield and
recommended 50' to 100'. So I added length and found no changes.
3. Decided to try 4 radials 12' to 15' long attached just below the coax
termination and stretched out (angled down), also resulted in no changes.
