If the only other element is the mast, and that's away from local QRM it all
works as it should.  Not necesasrily anything like as bad as the full length
of the feeder contributing to pickup.

And why's it "highly unlikely" the Tx isn't in the same box?.   I'm
assuming, but I'd certainly try a licence-free 868MHz wideband FM link, or a
2.4GHz FM TV one.  They're tiny postage stamp sized modules, and should
offer enough dynamic range where no strong local stuff is nearby.

Electronics has moved on since your day OM :-)
