Anyone have any ideas about what one might do with a television

owner's back yard.

I'm thinking radio astronomy. Might be nice to make my own radio map
of the galaxy. I'm guessing that this would work okay somewhere
between 1 and 10 GHz... which means making a feed horn... which is
easy enough to do.

What else could I do with this antenna? Other than covering it in
polyethylene sheet to make a really big bird bath...
==================================
Possible usage:
1) EME amateur comms
2) WiFi low power experiments (provided there is line of sight freedom)
I remember having seen a web site with reports (incl photographs) that
some youngsters bridged a 125 km path using off the shelf equipment and
dishes having a size like yours.

Hopefully you don't have just the dish but also a mounting pedestal and
perhaps even a motorised system .

Yep, got the pedestal and the azimuth drive motor.

125 km at 2.4 GHz? How's that work? What were they bouncing the
signal off of? That's definitely further than line of sight.

Hi, here is link:

Aha! Living in Florida for the last 15 years has made me forget about
the mountains out west. Yes, you can definitely go line of sight up
to a few hundred miles if you have at your disposal an assortment of
mile-high piles of rocks upon which to mount the antennas.
