Re: [amsat-bb] AO-40 Downlink Antenna Question

["Joel Black" <w4jbb@xxxxxxxxxxx>]

If you can find a DirecTV or Dish Network dish that someone is not using.
It's extremely light and provides a remarkable improvement over the linear,
"BBQ-grill" dish.

As soon as I get a chance, I'm going to get my system back on the air (I
should say back up in the air) and it will include an old DirecTV dish, DEM
preamp, and CalAmp31732 d/c.
