connector for rg59 coax

I am looking for ideas. The rg58 cable comes from mast top antenna, enters through the deck "clam" style fitting and then connects to the rest of the cable with splice-type connector. This worked well enough but every time I have to disconnect and reconnect it (like when mast is being removed) I cut a piece of cable. So, it is getting a bit too short and soon I'll have to rewire the mast if it goes that way

Standard PL259 connectors are too big to fit through the deck "clam" fitting. So, what else can I use that would be possible to separate and reconnect and would fit through a relatively small hole in the deck?

(I meant RG58 of course)

Brak—

A better solution is putting a PL259 on the cable in the mast and using an extended coupler to pass the connection through the deck rather than a cable clam. Far more leak proof and far more fool-proof IMHO. Also, the hole a cable clam requires is probably bigger than the one this requires. Hope that helps.

Looks like this:

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

First, get rid of the RG 58, replace with RG8x or, better yet, with RG213. Bite the bullet and learn how to terminate either so it isn't so much of a chore for you. If you're using RG8x, you can use the crimp type splices which can be separated when necessary and are much smaller in diameter than the PL 259's

Automotive style would work, male end will pass through anything the coax will fit through.

A bnc style is also much smaller than a pl259 connector, but larger than the cable.
Both types are easy to install.

replacing the cable is not an option - it is new (everything rewired 2 years ago) and it matches the size and type of installation.

what about those automotive connectors? do you have a link or something to take a look at?

BNC sounds like a good idea too but I haven't seen them in a while - don't remember how big they are (that goes back to old style Ethernet cable)

Sorry, should have called it a motorola connector!

-----------

Car Radio Antenna (Motorola Connector) Plug - VETCO.NET

------------

long link, but it's between the lines.

The same site has BNC and other connectors, the only female they show for the motorola type is a panel mount, but I know you can get an inline connector for them.

Been a long time since I've been in one, but radio shack used to carry them.

Ken.

For some reason the link is only 'CAR', radio isn't part of my link

Looks like I missed your reply. This looks interesting. There are two questions though:
1) this essentially means 2 connectors vs. 1? I can probably live with that, but in theory that's not ideal?

2) they don't say how long it is. I'll need a pretty long connector to go through my deck (probably about 4" in that location with the mast base, deck, liner etc).

West Marine seems to be the only place listing these items (at least I can't google'em anywhere else)

You need a Ham person

Look at Jubilee Enterprises and scroll down. I "think" this might be what you want. They come in 4", 6" and 12" sizes.

I *am* a ham person (at least in principle, I have a "general" license which I got back when you still needed to do "code" but I really haven't used it in years).

Cool, thanks for the link - this might be the way to go. I wonder if they are stainless.

I think you'll find that UG-363-x are not stainless. Amphenol are nickle plated brass. Some of the cheap ones are plated base metal. I think you might be better off using a BNC if that will fit through your opening. There is less loss with one BNC to a BNC to Pl259 adapter than PL259 to PL259 to UG-393 to PL259.
