(In fact, I'm just done a test on a digital TV, disconnecting the RF lead at
a joint: if the outer screen is in contact, I start to get a picture when
the inner core is 2 or 3 mm away from the centre pin! So the signal can jump
an air gap of a tenth of an inch,

But if the coax is also being used to supply power to an amplifier
(unlikely in the case of the OP) the dc voltage will not jump the 2 or
3mm gap.

The amplifier is plugged into the mains. They fitted a 13A socket in
the loft near the amp just for that purpose.

I've now seen that the FULL output socket on the amp is supposed to
have a terminator if nothing is connected to it. According to the user
guide I downloaded, the installer is supposed to fit this. He didn't.

Can one get a terminator from Wilkinson, or do I have to order one
online?

(Dunno what the effect is of not having the terminator present.)
