Why in Heaven would you or anyone want to do it? [I think there may be a Troll here :-) ] No troll, just a wild hair. I got to thinking of using mercury as the conducting medium for an RF antenna switch and then wondered if mercury could replace the upper part of a whip where there is low current and high voltage. The mercury changing length in a thermometer triggered these unthinkable thoughts. Imagine changing the current through a resistor in order to tune an antenna by varying the mercury level. No assumption here. I agree that this would be VERY difficult, although the "upper part" sounds feasable. Just replace the screwdriver motor & mechanism with a pump... -- Steve N, K,9;d, c. i My email has no u's. - 19 Different Servers! =----- |
