I could not find the original photos, so I took some new ones while I was out at various jobs this afternoon.
System box showing an HC12 module and a Sunray 1022 module in a mixer arrangement, using external SMA coaxes and a standard GME Kingray brand UHF booster amp.
The thick black coax comes from the roof antenna, the two thinner SMA coaxes are on the amp outputs, each one feeding its own RF module. The Kingray TV amp is modified to remove its 230v transformer totally, and feed the amp via the 12v UPS so it keeps on working if there was a power cut.

A Micromite 2 does all the work.
