I have 2 cable glands that need replacing on the aft deck of my boat. The cables have a Navtex aerial and GPS antenna fixed to them which are too large to go through any conventional glands and the wires are fed through 15 odd feet of bilges, bulkheads etc so I don't really want to draw them all the way back to thread the plug ends through either. Does anyone know of any type of deck glands that can split vertically to go onto the cable and then be fixed to a horizontal surface?

I don't know of any that split such that you can avoid having to pull the wire back through from inside the boat. However once you've done that, the Index Marine glands can at least accept the wire through with plug still connected. Not much use if you've had to detach the plug to get the wire out of the boat, though...
 

Those look a neat idea ... and quite easily replicated with a piece of teak and some sealant.

However for both NAVTEX and GPS I would have no hesitation just cutting the coax (inside the boat) and making a neat inline repair afterwards (twisted/soldered + taped .... not using connectors). I Challenge you to show any degradation to the signals.

Why bother, really.

My Navtex and GPs aerials are inside the boat. Fit them under GRP coamings. The signal degradation is minuscule. I was actually recommended by Garmin to not fit them outside. Glad I took their advice.
 
Index marine glands are what you need, you can split the rubber to go round cables and make holess to suit your cable. I did one which has 3 different sizes of cable going through it, no leaks

That still leaves me with the problem of getting the casing that goes around the rubber over the cable. No one seems to make one that splits, the cable still needs to be withdrawn which is what I am trying to avoid.

I think if you look at the construction I think that splitting the cover would not reduce the efficiency of the gland, though I haven't done it myself. I haven't seen a gland with a split cover. T he index gland cover has a taper to make the seal so can probably still work split.
 
Restlessl,

Many thanks for the link.

I too needed a way of replacing an existing gland without removing the cable and this is ideal.

I have ordered one for less than £4 incl postage from http://www.amazon.co.uk/Glomex-RA140-Roof-Mount-Antenna/dp/B0042ER5CG

I don't want a large hole in the deck so intend cutting off the part that goes through the deck and bedding it down with sikaflex.
