On my Nasa Navtex pro plus,I have managed to pull the cable out of the antenna base,it's the old style one with the stainless whip,i thought it was on a plug!Has anyone reconnected one of these and if so what did you do with the screen wire?I will also need to put a new connector(female) on the machine end,will a tv uhf plug do?
 
I don't know the antenna hoever there are some coax type connectors I think for cable TV which in effect allow the cable centre to push into jaws to hold the wire and the outer screen is held in by a screw over cover. It may be that kind of connector which you have pulled apart.
if as I suspect it is all molded plastic then you will just have to push the wire back in and hope for the best. You might even consider glueing the cable back into place. As it is receive only if it works it will be fine. The connection of the outer screen may not be critical unless it has an inbuilt amplifier.

As for a connector at the set you will need one to match what is on the set. If there is no connector just wire then a break can be made using a male and female of almost any type of connector. I would suggest the BNC type connectors are both reliable and simple to connect using a soldering iron for the centre pin only. If you don't want to solder then the TV aerial connectors are available (at least here) with a tiny screw to clamp the inner which unfortunately makes them very unreliable but convenient. good luck... olewill
 
Relax.....

It's ever so simple.

Inside the black box you will find a simple printed circuit board. It will be obvious as to where you re-solder the outer sheath and the core of the co-axial cable. You will need a replacement cable tie though, Slacken the black gland nut and free off the sealing washer before you start.

Yes you cn use a TV co-ax plug but wrap it in self amalgamating tape to keep the salt off afterwards.

Re: Relax.....

On the three of those I have owned, the screening was gathered to one side, twisted into a core and then soldered onto the large flat piece of printed circuit. Then it was secured with a small cable tie around itself and through two holes in the board at the bottom.
