Topband: Beverage Ant Thread

[Chuck Hutton]

Can you be more specific about "deterioration"?

   - front to back?

   - front to side?

   -gain?


It's my feeling that lengthening a BOG past .5 wavelength or so may bring a bearing into a null and move other bearings out of a null, just like a normal Beverage. The result may be seen as beneficial or not, depending on where you are and where the interference is.

Hi Ed,


600 feet is much too long for a BOG on any ham band except 630 meters.
Performance deteriorates as you lengthen a 160 meter BOG beyond
about 225 feet.


Because a BOG is so lossy, an unterminated BOG has significantly
reduced response from the backward direction.

I have also been planning my own Beverage antenna. My situation will only allow for a BOG which will be bidirectional and >600' long.

I plan to use the DXE kit, specifically designed for ladder line. My understanding is that 600' would be too long for a BOG on 160m. Though 160 is one application, my other passion is logging foreign BCB DX reception.

What would the happy medium be? Maybe two separate antennas?

Advice appreciated.
