Something I have wondered about as well. Assuming a voltage is put on the transmission line one would have thought the reason is not just phasing. I have some ideas but pure speculation. Surely someo

If one studies operation of the two wire Beverage, the only effect of reversing the two wire line would be in phase of signals arriving from the feed end. That would imply that polarity of the two w

1. It could be a convenient accident. 2. If on purpose, the answer is probably "Just in case this is useful". But then you would expect DXE to draw attention to it . 3. Useful that this has been "dis

I'll bet they don't put a DC control voltage on it. But I'm also assuming. On the other hand, a DC control voltage could be very useful to switch a separate run of open-wire line in and out of the ci

Hi Carl, I cannot think of any reason why not, assuming lateral spacing is within normal beverage limits (20ft minimum ?). 73 John _______________________________________________ UR RST IS ... ... ..

For the part of the question before the "such as"..... Yes, you certainly can phase two reversibles, but you won't be able to do it unless you can insure that a "top" and "bottom," or + and - , or br
