Default Beverage Ant. at ShortWave freq.

...
Are beverage antennas useful at 10Mhz (length adjusted for frequency).
Do they still have the same pattern?
Do you still place them 6 to 10ft off the ground?
Still the same termination resistance and input impedance?
Thanks for the info.

Mike,
the same rules for Beverage construction and use apply at 10 MHz, they are
being used with benefit on 14 MHz by contest stations.

Impedance for precise matching and termination should be measured for
particular setup - depends on height, ground conductivity.

For low angle performance length of 2 - 4 wavelength gives narrower beam.
For cleaner lobes phased or staggered configuration is preferred.
