[UK-CONTEST] Ecoflex 10 - Rotator loops was A3S - update

John

I use Ecoflex 10 on my install and its not caused any problems yet. Its been in the air for 3 or 4 years 
if memory serves me correctly.

I use it on my 6m antenna which is located at the top of my mast , the loop drops down through my HF 
antenna then I attached it to my rotator cage. My rotator gets turned every weekend when not working many 
times and occasional during the week. So if it was going to cause trouble it would have shown up by now.

I had the tower tilted over 2 weeks ago repairing my 6m antenna due to the winds and checked all coax and 
cables at same time all was fine.

I am intending to replace the coax to my fixed VHF antennas with Ecoflex
10 so was worried about the comment below about using it for rotator
loops.  I've used it in this application portable without problems but
it's a bit different using it for a long period in a fixed
installation.  I'd be grateful if the people who have had experience of
this would post their comments.

Thanks
