coax routing question

[rb]

Putting a "shortie" marine VHF ant on the boat. This ant is the one with a loading/matching coil at the bottom of the whip.

The coax comes down from the center of the coil. The base of the coil has a threaded female fitting same thread/dia as the male counterpart of the lay down mount. The lay down mount has holes in it to accommodate the coax in its journey to the radio.

Question is how the heck do I screw the ant onto the mount without the coax cord getting twisted to the point of damage? Is the idea that the coax will roll (twist) enough as I''m screwing the ant onto the base that it won''t damage something?

I know some of you have been there/done this, so tell me the way out of the problem.

Pre-Load the coax.
(i.e. twist coax in opposite direction before connecting to base)

Go to Home Depot and in the section where the tie wraps and electrical heat shrink are you will find Dielectric grease anti corosion GB brand I think is what they carry. Grease the fittings and they will not corode that little tube will last for a long time and its one of the best $3.00 buys you can make I use it on every thing electric even battery posts. Not one fitting has coroded in two years.Plus it makes removing a connector like yours a snap.

The coax connector should have a threaded ring to attach it to the bottom of the coil. the coax cable should not be rotating when the connection is made. The center pin on the end of the coax goes into the coil fitting and then the ring tightens all down. Seal up with "coax-wrap" or butyl tape and wrap with electrical tape.
