Direct TV question?
Hi Group,
I am starting to see the RCA's direct TV disk showing up for a fair price at garage sales. I have picked up about 3 of them so far. What I have learned on the internet is that the sates are around 12GHz and the down conversion is about 1 GHz. I recall a ham band around 10GHz and wander if anyone is doing work with them on the ham bands? How much gain would this antenna get at 12GHz. I believe the diameter is about 19 or so inches. Thanks! de KJ4UO |

Thanks! de KJ4UO Do a search under W1GHZ. Paul's site is exhaustive on parabolic relfectors and proper feed illumination. Dale W4OP |

Yes, and W1GHZ has an on-line book about using them as 10ghz antennas: http://www.qsl.net/n1bwt/contents.htm In the Twin Cities MN area we have nearly 2 dozen people on 10ghz, most with various types of DSS dishes. If you got the feed horn with the dish, you can sometimes drill it out to 3/4" for 10ghz. How much gain would this antenna get at 12GHz. I believe the diameter is about 19 or so inches. At 10ghz we typicly get in the area of 31-33dBi gain from the 19" dishes. Glen, KC0IYT |
