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.

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 unterminate

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

Thanks for the response. Perhaps I should think about two separate antennas? Seems the longer one may be just what I need for BCB. They would all be terminated and bidirectional with the DXE product.

Can you be more specific about "deterioration"? I experimented with Beverages for many years at my QTH with high ground conductivity. What I found was there was a 400 foot limit to the length, beyond

Hi Carl, Since your BOG is producing signal levels close to your regular Beverages, its not actually performing as a BOG. Which is a good thing! A typical 225 foot BOG has much broader 3 dB beamwidth
