Yet look at all the people who go to all the trouble of putting up a 3
element beam, then think that the 7 dB gain over a dipole actually makes
their signal louder. Or get a 500 watt amplifier for their 100 watt rig.
Silly fools! Old wives!

back on topic,..

i still ponder if i put power into a superconducting antenna if their
is no resistance, and a given about of power would therefore 'stay' in
the antanna longer ie no resistance and a sorta flywheel effect exists
the fields would have to exist longer for fixed-given power , ..

seems that all adds up to more than a trival gain

looks like ill have to use some cheep material like copper or something
elese i can make superconduct unless i can use a supension of
conductive materials into a coolent itself an make a tube that will
radiate while being superconductive just cause i wonder if that will
work as good as a stp based liquid antenna

who knows maybe i'll stumble over 3xtra db

will the antenna stay resonant as it nears criticaltemp? and reaches it?
