Signal dropouts (signal strength 30% - is this too low?)

This is getting tedious. Even a trickle on the RF Out should register with the TV. That's the last I'm saying on the matter.

Well yes, I agree. But for different reasons.

Is the centre connector on the RF socket splayed or lose?

The other one is the centre contact being pushed in.

The other one is the centre contact being pushed in.

And of course the connector being ripped off the screening can. BTDT.

So you are postulating two faults not one.

I would.

I start from the premise there is one fault to explain all the symptoms, it is unusual for there to be two independent faults (unless perhaps the pass-through fault has been there for a long time).

If it has been damaged by e.g. lightning, then it is more than possible for there to be two faults.

Why do satellite TV circles use "transponder" at all? They're not transponders from the user's point of view (or even a technical point of view) - I take "transponder" as meaning a device which responds to a received command by transmitting a response which is not the same as the stimulus. Something which simply passes on what it receives is a repeater.

I disagree. A satellite transponder does a frequency and polarisation change on what it receives, amplifies and re-transmits. This is not a repeater. The response is different to the stimulus, although the information content is identical.
