Hello and thanks for all the replies on the list and directly. I realize now that I had not understood the way that bidirectional Beverages work when they use only one coax. Perhaps there are others who have made or are making the same mistake so I will explain where I went wrong.
I thought that in order to change direction some sort of switching was used but the only switching is switching the coax from one conductor on the ladder line to the other. The "magic" is done at the far end of the antenna in the termination transformer/box. In fact the signals from both directions are both available all the time and so the way to give multiple receivers in the shack access to freely choose which direction to listen to is simply to run coax from each of the directions back into the shack. Luckily thin coax is very cheap!! Then there are various ways to feed the signals to 2 or more stations. This clearly shows what happens when you buy commercial products without doing your homework first!! Sorry. But thanks a lot for your help everybody. 73 de Andrew OZ5E _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
