TV RF connector cont'd

Thanks for all the help!!! Can anyone identify the value of the Cap?

Here is a pic of the cap and the sticker on the metal box.

Asimov is right, there is a 2-4M ohm resistor as well

My guess(tm) is that the "C131" means 130PF.

How about a picture of the whole isolation block?

I would not even try and find the capacitor as a part, it is a special spark
gap isolation capacitor that is not typically found from many parts
suppliers.

You can buy an ENTIRE isolation block for uner $10 from MCM with your next
order.

Then you would be guaranteed proper isolation for safety.

In addition the number on the block looks a lot like a Goldstar part number
and you can probably call any Goldstar parts dealer for an exact replacment.

A what? A "special spark gap isolation capacitor" sounds fishy to me. A
spark gap might be used in a lightning arrestor to discharge to ground, but
these antenna isolation caps are not spark gaps, they are high voltage
ceramics, aren't they? Why would you want to isolate the signal line only
to have it discharge over a certain voltage into the tuner? Can you even
build a spark gap that will have the ability to pass significant RF like a
cap? Is this some type of capacitor that is designed to fail as an open
circuit instead of a short, maybe? Maybe they are just old style single
layer ceramics for this reason? I'm not sure, but I'd love to see some
description of this design so we could learn something.

Certainly there is a potential for compromising the safety of the system by
using inferior parts or wiring it incorrectly, and I agree that these
isolation blocks can be had cheaply enough that it is not worth the trouble
to find replacement parts and repair them, but lets not misinform in the
name of safety. Most of us come here to share information and learn, not to
be baffled by bullshit.
