Hi
The fancy F connectors are indeed waterproof if:
1) You have the right cable
2) The cable and connector match up
3) The tool and the connector match up
The auction sites are a great place to get samples of connectors and tools that
apparently work with no known cable …
If you are not
Sorry, not neoprene but self-sealing polyisobutyl tape, very effective for
the outdoor antenna work**. I have recently opened a sealed connection,
after 10 years, and the protected connector appears as new.

It's a very useful material, also called Self Amalgamating Tape.
Been using it for years for all sorts of outside cable work.

Of course, everything has to match, the cable, the connector, the
pliers. Be careful with the inner conductor. It's good

Hi
A simple way to look at filter stability is to first look at group delay at
10 MHz (or what ever your signal frequency is). The higher the group delay,
the more likely you are to get into the sort of trouble you thinking about.
Low Q / wide band filters are your friend in this case. Band pass
BTW - 3M Scotch rubber tape is regularly used in the offshore industry to
make waterproof connections to 6000m/10,000psi. I use it on any/all
outdoor signal (RF/Microwve antenna connectors, amphenol, etc) connectors
as well. I cover the rubber tape with a layer of electrical tape (Super
88), and

Water has a dielectric constant around 60 compared to plastic that just over 2. So if water gets into the connection
there's going to be problems.
It turns out that Silicon grease has a dielectric constant very close to plastic so filling an open RF connector with

this is a very good note,
many thanks for this very interesting information and the work behind!
I will try to implement the new code and a new processor without

You must be ex-Navy. We did the same thing with a final coat
of liquid rubber. 3M scotch coat. On the ships I could open a connector
that had been to sea for years and the connectors were clean as they were
when installed. I still use this approach. Very solid and as I mentioned
