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 circuit (that is, to remotely change the length of the Beverage). I have often thought of doing that myself, to change the beamwidth of the Beverage for use on different bands. Maybe someone will hang a voltmeter on the feedline and let us know what they find, as the Beverage is switched in both directions. But I think if we open up the reflection transformer enclosure, you will not find a relay. 73, Mike http://www.w0btu.com/Beverage_antennas.html _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
