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! Roy Lewallen, W7EL 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? |
