Never heard of it prior to your post but it would definitely help.
I hate to be off the air but it's time to do some improvements to the beam.
I removed it from the rotator and the beam is now at 10ft, which is a workable height. I will do several things, such as painting the PVC/fiberglass (provide some UV protection) and retensioning elements and support guys.
I'm going to put some more bend in the spreader assemblies. After I do that, I will retension all of the wire elements. Of course I will also play with fine tuning again, as 21mhz is a little high on SWR.
It's been a good antenna. It's been in the air around 4 months now.
Found out what my tensioning problem was: the end segments of the crappie poles had collapsed inside the larger segment. This only happened on the ends. If I glue/clamp/pin, it should solve the tensioning problem and I probably won't use the bungee cord.
Also, the plastic mil spec zip ties break easily after only 4 months....
Raised the beam up from 15ft to 25ft and it seems to have made a world of difference...
