I miss the old C band days. There was always something cool to watch. Live, unedited news feeds were awesome. Lack of commercials, even better.

They had to go an ruin it.

I remember them as well. In the early 1990's i built a new home in an area not served by cable and DTH satellite was not yet available as it is today. I had two channels that were snowy and one crystal clear off air and that was it. One day while at work I received a call from Broadcast News in Toronto telling me they were switching out hardware and a crew would be down sometime in the next couple weeks to change out all the satellite news equipment we had and that the old gear was being made available to anyone on-site that wanted it. I jumped on it quick and ended up with a 6 1/2 foot Ku band dish with a dual feed C-band LNB for V and H polarity as well as a switchable dual polarity Ku band LNB and a dual C/Ku band Pansat receiver. I had a lot of fun withj that for a few years until cable came out the road and then dropped that for DTH satellite. Most of the time I parked the dish on Galaxy 4 ( or was it Galaxy 5?) I had to manually move the dish but I made a chart and mounted a pointer on the dish mount. I knew that the yellow dot and 16 inches of screw thread was Anik E1 and the blue dot and 7 inches of screw thread was Galaxy 5 etc. I could go out and swing the dish and measure the amount of screw thread on the elevation control and come back in and have a crystal clear picture. It worked great.

Not to start up an old topic... seeing there was never any pictures... But if the antenna was horizontal, with the tip pointing to the north, wouldnt this talk east and west? He was probably getting his rejection from the fact it was mounted horizontal. Not because of the dish. Thats the take I took on it. I think this is the Null area many were talking about. Which would be directly in front of it, which is the actually direction he was intending to talk. Not to mention Id have to be proven the swr could actually get that low on such a contraption... And did I mention I seen guys talking off coke cans with a tuner... Worked, for like 1/2 mile of open field... NOT 200 miles.
I've built some crazy antennas, but are based on good theory, but nothing like this... I spend a LOT of time building, trying, tuning, and making new antenna. Love it! Yet I dont think I would have ever considered this one.

Nope. Every time I am in the attic and see the dish I remember this thread.

WHy I've not gotten around to it. But I said I would, so in time, I will. . .

Homer, what do you have in mind to radiate at resonance using a dish?

I don't have anything special in mind. I just said I'd hook up a mobile antenna to a dish and see what happens. I figure it will be the chore of a few minutes and have no expectations but to do as I had said I would.
The real thing will be that I choke the coax and see the results without the coax being used as part of the antenna.

I know that this is an old thread but this is the first time I have read it,
For interest sake... I have experimented using a Foxtel sat dish in the past set up as a reflector with a folded dipole for our uhf cb band (477mhz).
It worked ok, nothing special but for limited space it did the trick when I was living in a high rise apartment in the city
