Just wondered if anyone knew of a UK source of an inline one. Thanks anyway, at least I know they exist!
It would appear that at one time Antiference used to make an in-line balun (TRR/V/SP) for use at the receiver end. It is mentioned in the FM aerial section in Hi Fi Year Book (HFYB) 1974 and then in most issues through to and including 1980. A copy of the HFYB 1980 entry is attached, and I have found a picture from another book. It might be worth checking with Antiference (if they’re still around) to see if its balun remains available. It looks as if it was a response to the prevalence of imported FM receiving equipment fitted only with 300R balanced aerial inputs, rather than with 300R and 75R options.
