Need custom modules for HV video

[Vince]

I'm trying to figure out how to get the overlayed video from my Homevision
unit upstairs onto my TV downstairs?

Thinking about it, I could do with a pair of custom KAT5's configured as
follows:-

Each has video in both directions.
Each has a pair of RCA Phono Connectors.
The TV KAT5 gets its power from the HV KAT5 module.
The Cat5 pair not used to be used for HV I/O.

So how about it Keith? Have you the bits so I could put these together
myself?
