Recently, on a whim, I bought one of these <http://www.ebay.com/itm/12V-8-Channel-Way-Relay-Output-RF-Remote-Control-Switch-/130545242235#vi-content>, thinking it might be possible to use it to switc

Velleman kits has a similar widget that I've used (with a wired control, but they have an RF module that plugs into it). WHat frequency is the remote at? 433 MHz? A small Yagi might do quite nicely.

If you can tap the rf off of both ends (grab it before the antennas), you should be able to duplex the signal onto your beverage feed line. Then, you are only limited by the loss of the bev feed line

For a receive-only setup, you could easily run the 315/433MHz control signal up the coax, along with 12V DC power and the returning signals from the Beverages. A few inches of wire threaded under the

when I was looking at 2.4GHz for HF antenna control, I was more worried about overcoupling and having the HF destroy the 2.4GHz stuff (or, at a lesser scale, having it saturate the front end). Say th

I did say "for a receive-only setup". Duplexing UHF on a HF transmitting coax requires more thought and planning to avoid overload or damage, but can certainly be done; and Pete's application with Be

Thanks to everyone who responded to my message recently about this device. I've done a bit more reverse-engineering/testing, and thought the result might be of interest. If the following writeup is u
