[amsat-bb] Re: J-Pole Antenna

[Jeff Moore]

I wouldn't recommend a J-pole for satellite work unless you expect to 
only work sats on the horizon.  The J-Pole antenna has a low take-off 
angle and almost NO radiation overhead,  an plain 1/4 wave ground plane 
antenna would work better for the sats.



J-poles are great terrestrial communications antennas, not so much for 
working overhead satellite passes.  An Eggbeater or quadrifiliar antenna 
would be a better choice.
