Thanks for the comments – it is a hairpin design. It is an M2 6 element 15 that
was built using their 15M6-125 antenna and converted to their 15M6DX ... so I
refer to it now as a 15M6DX-125. Anyway it has a fiberglass center insulator
with thick donuts to ensure there isn’t any creepage along the fiberglass...
and if it were anything related to that it should have done it when I hosed it
down (lowered to 8’)... I couldn’t really get it to change with a hose.
Its off the tower now – had to move on (take advantage of clear days) to
testing the 20M5LGS made from a 20M5 ... its now on the tower at 8’ up with
high winds so its not going up any higher until the hills are calm.
I’ll continue to test the 15 on saw horses. What I was seeing I’m sure will
show even at that height. And once again: whatever design wise might be
suggested it has to be remembered this is a near exact duplicate of another one
that didn’t have this problem. So I’d guess it has to be either related to
construction or possibly a deficiency caused by being used. The latter
shouldn’t be a problem – I’ve dealt with used antennas before and never had a
problem... but it could be. Please write direct if you have any other thoughts
that come to mind.
Gary
