Would this do?

Thank you for that link! It is a good start.

But, by the time I got out of there, I was well over $400 - not what I would care to spend for something that would get used twice per year for a hobby I do not have. I am trying to be a full-service OTA provider for the good of the club, and to help the other vendors as I do with the AM & FM-stereo transmitters. UHF TV would close the loop covering all the relevant receivers and tuners.

Thanks again!
