Default VHF Antenna bulkhead connector?

I am in the process of installing a Standard Horizon Eclipse VHF and Shakespeare 5225-XT antenna. The VHF will be flushmounted in my center console and the antenna will be mounted to the starboard side of the console.

The antenna directions say to use at least 3 feet of the RG8X cable, and supply a PL259 connector to connect the cable to the VHF. I could just run the cable into the console right at the antenna mount under a wire cap or through one of those small round stainless gasketed covers and make the mounting essentially permanent...

However - is it possible to buy some sort of female/female bulkhead mounted connector whre by I could have a short (maybe 1ft) RG8X pigtail with a PL259 on the antenna connected to the bulkhead, and then inside the console a 3ft length of the RG8X with PL259s on each end from the bulkhead connector to the radio?? The basic desire being the ability to easily remove the antenna from the boat in certain circumstances (family days on small ponds, etc)

#1) Do they make such a bulkhead connector and where could I buy one of those and 2 addl't PL259 connectors??

#2) I would still have an overall length of RG8X in excess of 3ft per the directions with the antenna, but only 1ft from the antenna to the bulkhead and a second 3ft section from the bulkhead to radio. Will this degrade performance??

Thanks for any advice...

Any conection or connector that you add to a vhf transmitter will degrade the signal but not enough where you or I would see or hear the difference unless we had some high end measuring equipment.

I used your idea on a t-top that I wanted to take the vhf antenna completely off......the last time that I didn't the antenna (folded down) put a hole in the winter cover I had on.

Do the project and here is the connector that you are looking for and probably be found at your West Marine and if not try a GOOD Radio Shack.

The problem with adding connectors and new pl 259's is that most people try soldering for the first time and screw the soldering job up.

Paul, I would suggest that you leave 3' of antenna coax on the antenna end also.

(EDIT)....I also would suggest that you put a rubber boot on the outside connector and to have your coax comes from the lower side of the connector so when you take the big splash (wave)over the side, the water will run "down" and away from the connector.

Good luck........Booby

I believe they also make these in gold plated now. If you can, use the gold plated connectors, as they will never corrode, and all the others will eventually start corroding.

Paul in NH... Look at it this way...you increase antenna joints 200% and expose one connection to the elements if you use the bulkhead fitting . I'd go with a SS clam shell with a drip loop. Put a 3' section inside the CC and into the radio. It has been my experience that you will seldom take the antenna off the boat. I'd rather have a solid connection to radio Vs convience of removable antenna. Just my thoughts. Or you could use a throught bulkhead seal Vs SS clam shell. Either way you eliminate two connection. I hate PL-259 connectors...one is too many!

Thanks guys!

I found a few sources for the chromed bulkhead and PL259 connectors. I have been unable to find a source for the gold plated ones, but I'll keep looking.

I think Im going to try it out. BUT... Im going to leave a 3+ ft section of cable on the antenna side (i.e. outside the console)in a neat coil. That way, if performance is compromised by the additional connections, I can always go back to a permanent installation with one of the stainless through bulkhead seals and a single connector at the radio, because Mumblerone you do make some valid points.

But I really want the option of a simple disconnect of the antenna completely, or the ability to purchase and swap in a 3-4' antenna. I definitely can see the advantages of taking off the antenna when Im lake or pond fishing with the kids, or for winter storage, etc...

Thanks all again,
Paul
