Default what to do with extra coax in elec box

i am replacing vhf antenna and installing new gps. antenna comes with 20 ft RG-8/x cable,gps antenna has 30ft. i do not know how to reconnect fittings to cable, so i dont want to shorten cables. my question is- if i coil up all this extra cable inside small elec. box will i be causing noise between vhf and gps ? i only need 5ft of each. sounder is also located in this box. thanks for any help.

My Gps and antenna cable run right next to each other and I have no problems. It is really easy to cut off the extra coax cable from the antenna and put a soldered fitting on. I have never cut a GPS cable though as I was not sure about a splice. Shakespeare makes a nice center pin connector that is really easy to use for the vhf, no soldering required.

I've cut VHF cable off, no problem. Have used long and short GPS cables, no problem. I wouldn't cut the sounder cable though. I'm not and expert here, but something in the grey matter says it should not be done; or lengthen more than 'x' number of feet, for that matter. I'm sure you'll get the right answer here.

I would not cut it. Should you be out of range and need emergency use, you could "physically" raise your antena or locate a offshore rig and carry your antena up a few feet to increase your range.

you need to cut vhf cable to reduce power loss, also if you coil it up you create a electro-mgnetic field that could mess thing up. do not cut you vhf cable any shorter than 3 or 4 feet as this to will create problems.

Grouper,
If you don't have the experience replacing cable connectors don't cut.
The radio cable could be cut but why cut it and have problems with the connector.
Coil it up......by coiling it up I mean coil it up but then tie it together with tape or wire ties...... make it look like an new extension cord you would buy at Wal-Mart.
If you coil it into a round coil and if there are enough coils technically tpp517 is right about creating an inductdance but I don't think it would effect you where you or I would notice it.......but anyway to be on the safe side tuck it up in there nice and neat, it will be fine.
Good luck.............Booby

Right again booby. Don't worry about the inductive or capacitive coupling from the coils, the coax shield, which is grounded, prevents any significant radiation.
