Re: Newbies! Hard-Sats destroy AMSAT.



I also found plans for using a $35 Alliance U-110 rotor for an altitude /
azimuth rotor system.  I'm combining plans from the 1993 ARRL Handbook (pp.
23-14 - 23-15) and from http://web.wt.net/~w5un/readout.htm.  I estimate my
total cost for this system will be around $150.  The most expensive pieces
being the two rotors and the two DVMs for the readouts.  That's a far cry
from $600 for a G-5500 and the U-110's will handle up to 5 square feet
windload.  That's more than enought for my current Cushcraft antennas (an
A144-20T and 738XB).

You know, I'm thinking you could get two Arrow antennas and phase them so
you have circular polarity.  You now have an antenna system for $250 right
or left-hand circular polarity with rotor system.  Howard, isn't this how
your previous antenna system was engineered?

I get tired of people thinking they've got to fork over a lot of cash to get
on the birds.  Maybe it's an excuse - for whatever reason!
