Thanks. No, I did not have preamps at the feed point of the Beverages.
Is the sensitivity of a one wavelength Beverage low enough that a preamp
at the feedpoint is needed? Loss in decent coax is pretty low at 2 MHz,
and where I live, electronic noise has gotten high enough that I can't
imagine it being a limitation. My reversible one wavelength Beverages
(one EU-VK, the other SA-JA) point to noisy homes facing EU and JA, so
they've become next to useless.
My 8 acres are in a dense redwood forest, with terrain that varies by at
least 50 ft in elevation, so any of these vertical arrays are out of the
question. I am finding some benefit from an array of two VE3DO loops
spaced 5/8 wave, but one of them is quite close to the noisy EU home,
and points at it. :) I'm phasing it with an NCC-1, which allows me to
shift the pattern between northern EU and New England.
