I can understand the mistake of fitting the cable grip upside down,
given that the cylindrical metal shroud of the plug often has a
conical indentation at the cable end into which the conical end of
an upside-down cable clamp fits nicely. I've even seen plugs with
the clamp already inserted upside down so a punter would naturally
assume that when he has removed it to fit onto the cable it should
remain in that orientation.

I've never heard of soldering the central core to the centre pin of
the plug. I was told to use fine-nosed pliers to crimp a slight
kink in the core so it will make good contact with the inside of
the centre pin.

oh dear.


It was a lot more important to solder the inner when TV was delivered
via VHF especially Band I

I'd expect far greater losses from an un-soldered joint at Band V


It's a commonly held view given that feeder losses are so much greater at
UHF, but it's wrong.

How about reading the manufacturers tables?
eg: URM43. 100MHz loss 13dB/100m
600MHz 34

URM67 50 MHz 4.5
800 MHz 18


He's right on that one!.

And thats taking decent cables, not the ones sold for TV use that have
sod all copper in them.

I believe the noble member for Rotherham Lord W Wright did quite a bit
of work on that a while ago?..
