Very interesting! I have a set of
530 ft beverages about 2 feet high.
Last summer, I inserted a relay at
the 400 ft point of one of them,
and A/B'ed 400 ft vs 530 ft. I
tested on broadcast band, 160 and
80. I couldn't tell the difference!
I also measured the current along
the wire, and it was down considerable
by the time it got to 400 ft. The
attenuation was more severe as
frequency increased. I also tried
raising the beverage higher, but
it didn't change the current distribution
BTW, I found a big improvement going
from 10 to 2 feet in height. If you
can possibly do that, it might help
a lot more than extra length. I was
going to make an adjustable height
Beverage that I could lower for DXing
and raise for mowing. But that was
before I discovered Roundup.
