Satellite frequency changeover relay

[Thala Dan]

Anyone have any idea where I might look for the following......can't find anything with Google....lots of 50 ohm RF stuff, but nothing for Sat freqs and impedance.

Looking for a SPDT 75 ohm impedance changeover relay that can handle Sat IF range......'F' connector in and out......and preferably with a low voltage DC coil.

I want to remotely switch the output from a single-output LNB to different inputs on a multiswitch.

I have some sealed 12V conventional relays, and a number of reed switch relays which, at a pinch, I can make up into the switching unit that I need, but it would be a lot more convenient if such a device was available off the shelf. Also, a home-brew rig will most likely present SWR, and hence insertion loss, issues (although possibly not earth-shattering).

Will be mounted inside, so doesn't need to be weatherproof.

Any ideas?
