How to get a Perfect Beverage - Antenna special on hard-core-dx, how to install a perfect Beverage

Why terminate a Beverages - Terminating the far end of the Beverage makes it unidirectional. It also makes the receiving angle of the antenna lower.

Poor ground, better Beverage - Poorer conducting earth beneath a Beverage gives better performance

Beverage Antenna Construction - Types of beverage wires, choose best supports and insulators, multiple antennas at one feedpoint, all well documented with photos and exaustive explanation.

Beverages: How Short Can They Be - When we think of Beverage antennas, we automatically think of several acres of land and lots of wire!

Antenna Noise and Signal Cancelling at LF - By using the signals from two antennas, controlling their relative amplitudes and controlling the phase of one of them, unwanted signal or unwanted noise can be phased out. Circuitry is described which uses the signal from a wire antenna to provide selective cancelling against the signal output from an LF loop antenna.
