I suppose it might be a combined 75 ohm/300 ohm connector. Try your
FM downlead into any pair of holes, see which work best! I suppose
it might be worth looking for a voltage on any of the holes first,
just in case it's some special arrangement for e.g. powering a
mast-head amplifier.

I've only got the boggo bit of wire with a connector on the end as supplied
with cheap mini systems and a proper RF connector aerial. Nothing that'll go
in the holes provided.

Oh, don't be so helpless! Bodge it! :-)
