Easy enough to "fake" with a powermid or similar IR-UHF-IR transmitter/receiver combo. My FTA recievers are located in the utility room and send TV throughout the house.
I was going to say the same thing, because that's what I do too, however it depends upon what the OP wants the UHF capability for. I use the powermid things from everywhere inside my house, and I agree that they work great, however the place I've missed the UHF capability most has been outside at the dish. With my analog receivers, I used to be able to use the UHF capability to move the dish and change channels, etc, while outside aligning the dish, with the receiver still inside (I say "used to" because my UHF remote pretty much died, and I'm stuck using a universal IR remote now).
I've tried running an extension cord out to the dish, and plugging in one of my powermid things, but it doesn't reach back into the house. I have been meaning to try another device I have, which is a universal remote with UHF capability, however I don't have great hopes for it either, unless I could get it to send to one of the powermid things, however the one time I tried THAT, it kind of went beserk, and the two remote extender things started sending gibberish to each other.
I've never used such things, but there used to be some computer based IR emitter things that you could buy. If these are still available, another option would be control via computer, and if you hook up a wireless LAN, this can be from any location in and around the house. I was able to get my laptop up on my LAN from out at my dish, and I could control my TWINHAN/TSREADER system which is on a desktop PC down in my basement from out at my dish. Only problem was seeing the laptop screen in bright sunlight.
