[Antennas] Beverage On Ground

Mon May 5 20:40:57 EDT 2008

Due to the higher ground losses, a BOG 1000 ft long may only
utilize a fraction of the length. At my QTH a beverage 10 feet
high peters out long before 1000 ft is reached, let alone a BOG.
If you make the BOG length beyond the stage where it is loss limited,
you don't need a termination resistor, since nothing reflecting off
the end ever makes it back to the source. My first beverage was
1300 ft long. It had 40 dB front to back, regardless of termination.
Of course the last 500 ft or so was doing nothing but acting as a
termination. It contributed nothing to the received signal.
Also you do not run it "around the perimeter". You run it in a
straight line.
