[amsat-bb] Antenna Setup

[Rupert Hamblin]

Hi Guys,

Really appreciate all your comments / feedback here, just one additional 
question from me,
In real world / every day use - what difference does using X-Pol (Cross 
Polarized) antennas versus
a straight beam mounted vertically ? - How much of a difference does it 
make to the received
signals ?

Thanks again for your thoughts..

Cheers

RH
