recognize this vhf connector?

[tim_ber]

This was on deck of boat I am helping out with.
Never seen a vhf plug like it; used to pl259.
Is it easy to clean? Is it ok to reuse and is it easy for a half intelligent person to figure out how to connect the co-ax to it?
Thanks in advance again.View attachment 31976View attachment 31977

It's an N connector. Google for fitting instructions.

It's an "N" type UHF socket - an upgrade to the older PL type

I've got one but never used it - what does it look like inside?

If you're feeling cowardly, the above eBay seller does adaptor plugs....

This is the inside, I'm wondering where the braid goes. About to follow John's advice re: Google now I know what it is called thanks.

Far better than the Pl 259 things, never mind the fact it is constant impedance (50 Ohm) which the 259 never is.

When correctly assembled & mated to the socket it is waterproof so ideal for deck connector.

Good quality new ones are 'reasonably' waterproof would be the way I would describe them. Once its connected some amalgamating tape over the whole thing would be a good thing...

I do agree that they are good connectors. To get the best performance from them they need to be fitted carefully and accurately but for Marine VHF it won't be too critical.

As Salty John says, google for fitting instructions, but make sure that you've got the instructions for that particular 'N' connector as there are variations for different co-axial cable types.

I had to get an experienced electricist to fit a new plug to mine, I had tried and failed, they are a bit of a sod to assemble, but they work well once done. The clever electrician type person also struggled to get the connector and all it's bits assembled and working. I must admit it was very cold and windy which didn't help, neither did the fact that I had trimmed the cable off a bit too short. (Oops!)

There are dozens, perhaps hundreds of different 'N type' connectors. Each made for a specific cable size. They are used on high frequency test equipment up to about 6GHz, so useful well above the VHF range.
At VHF, there is very little penalty in using a BNC to N adaptor, and a BNC plug if that's easier to get and fit to your cable.
The N is robust and good ones are quite water tight.
But only if fitted properly to the right cable.
www.rswww.com have a fair range, Maplin might have a few...
