Thanks for the positive feedback from all. I'm not looking for a 'killer'
antenna, just something small but more efficient than the Cushcraft A270-6
that I am currently using. I have it fixed tilted at about 25 degrees atop
my 33' foot 'pole tower'. I made some modifications to the feed part of it
and retuned the gamma matches and it works OK, not great, but OK. I'd like
to replace it with something with a little more gain on 435. It works very
well on 145.
I'm either going to clone the Arrow (VE2ZAZ's clone) or buy a bare Arrow
and weatherize it. Got all winter to ponder it.
And yes, Jim WA4IVM, guess we are a couple of old fogies...
Looks like we both got our tickets in the same year, and got retired the
same year. 30 years with IBM and 6 years in other places as a consultant was
enough for me. Glad that part of my life is over.
Thanks again for all the comments and 73 ...
