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.
