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.
