High voltage switch/relays for antenna?
Hello:
I am contemplating constructing an antenna where a center-fed HALF WAVE will be bent in a loop, only to be isolated at the almost-touching ends by a relay or some other means of a remotely controlled switch. When the relay contacts are open I will have very high RF voltages between the contacts, probably "a few KV" or even more. Are there any suggestions on where I could find a relay, if any, for this? Or any other means for doing this? An additional constraint is that the switching device needs to be light and small (say, 1-2 oz or 20-50 grams). Some ideas I have come up with a - A small vacuum relay (supplier, type?). - A home-made relay, providing more contact spacing than usually available. - A DC-motor (toy-type) driven mechanism to open and close contacts. - A mercury switch that could be tilted to make or break the contacts. - A string-operated switch to open and close the contacts (would run up the antenna mast). Any comments or suggestions? 73 - Kristinn, TF3KX |
