The beverage antenna seems to be an excellent mw receiving antenna.

1) Is there a reasonable minimum length?

2) The beveage is supposed to be grounded through a resistor at the far
end. What type of resistor and how much ohmage?

There are several antenna books which make the same suggestion, so I have
no way of citing the original source.

They all sugest you take a mechanical hour timer and connect a terminating
potentiomiter to the shaft of the timer, start the timer and record the
noise from the antenna. Note where it reaches the minimum.

A more modern possibility is to use two HT's and have one person monitor the
noise, while the other adjusts the resistance.

You probably could do it with a laptop, wifi and skype, but that may affect
the results.

Geoff.

The answers to all your questions and some you haven't thought of are
answered in ON4UN's book: Low-band DXing. See ARRL for the book. Great
reading any time.

Hello, and the chapter "Long Wire and Traveling Wave Antennas" in "The
ARRL Antenna Book" gives theory and practical Beverage antenna designs
for one- and two-wire types. For the case of a one-wire Beverage a
non-inductive terminating resistor in the range of 400-600 ohms is
typical. It should be emphasized, however, that the precise value of
the termination has to be determined by experiment for optimum rejection
of rearward signals. Sincerely, and 73s from N4GGO,
