Radial wires of any length are an effective Beverage termination,
preferably laid on the ground to minimize undesired signal
pickup and to avoid the need to use a resonant length.

Elevated radials should be resonant length and opposing each
other to cancel signal pickup.

For a permanent installation, chicken wire laid on the ground
is a superb termination. If laid under gently sloping wires at
each end of the Beverage it forms a transmission line that significantly
reduces unwanted pickup from what would otherwise be roughly 7 foot
omnidirectional vertical termination wires at each end of the Beverage.

On K1N we had two ~ 100 foot length radials at right angle at each end of 
the Beverage. Because of the thick bushes, the radials were about 3 feet 
above the rocky ground. The antenna worked reasonable well (18 JA QSO-s and 
hundreds of EU0-s.)
