AFIK its right in the middle of the 70cms ham band in UK. a web search for 70cms pre-amp should find something. Failing that the " remote imaging group " may have something. But did'nt he say it was a BIM tranciever?, in that case it may be difficult to get into the RX path. I'd personally go for a beam antennae, with the module at the feedpoint to reduce feeder losses, if directionality is acceptable.
