RE: [amsat-bb] RS-15

["Kevin Muenzler WB5RUE" <wb5rue@xxxxxxxx>]

Don't use a vertical antenna system.  You need to have 
an antenna system that is efficient with high angles of 
attack. Very MINIMUM would be a horizontal 1/2 wave 
dipole.  I have a set of inverted-V antennas that are 
90 degrees apart.  They use the same pole and feedpoint.  
It looks like a plastic pole with 4 guy-wires.  They 
are fed with 1/4 wave of 75 ohm coax into a T connector.  
I also do have a pre-amp which is NECESSARY if you want 
to have a real QSO.  You also need at least 100 watts 
ERP on 2-meters.  With this I rarely get any meter 
movement on my HF rig during a QSO.  RS-15 only transmits 
about 1/4 watt ERP so the emphasis is really on the 
downlink receiver system.
