[TowerTalk] New antenna?

[David Gilbert]

"Nothing scientific" Exactly. Receive is a pretty bad way to compare 
gain unless you did so with instrumentation. Signal to noise is how we 
usually judge signal strength by ear, and if the gain is less so will be 
the noise. I can hear a LOT of stations on antennas that are so bad on 
transmit that nobody would be able to hear me. Your "slightly less" 
could easily be several dB, and "not bad for an old design" is hardly a 
recommendation when better designs are available. Dave AB7E
