I have a full size 3 element, 20 metre yagi, which I inherited from a
silent Key for the effort of taking it down, along with a windmill tower
and very heavy radar rotor.
If I were to put it up someplace on my very modest antenna farm, could I
still qualify as a Tribander/wires category?
Or, if I put up a W8JK fixed wire beam for 20/15/10, would it disqualify
me as from the Triband/wires category because it CAN work on 17 and 12
metres?
I'm thinking I need a bit more "punch" for my QRP effort on 20/15/10
because lots of quite loud signals couldn't hear me on their end, even
though they were S9+
A W8JK beam would be easiest - I could point it toward Europe and hope
to work a bit more from there. As is, it was pretty slim pickings to
Europe with my 80 metre dipole fed with ladder line.
Also, I'm thinking of putting up a full wave loop on 80 metres at about
35 to 40' high. Would this be considered a multi-element antenna if I
used it on 40 metres? How about 20/15/10? I haven't bothered to
research the directivity of a multi-wave loop, but I do remember vaguely
that one gets directivity and gain, and the radiation angle gets lower
as the length of the loop in wavelengths increases. I think I read
somewhere that a "V" beam or a Rhombic would NOT be considered for the
"Wires" category. which seems logical because one can get quite a big of
gain from a muti-wavelength v-beam or Rhombic. Of course the horizontal
beam width of a Rhombic gets very sharp when the length gets very long,
so there's a big tradeoff.
I see that most of the QRPers don't claim TB-Wires, so I'd like to stay
in that category for future efforts.
