Short antenna cable

[SeaDancer]

I just took my Icom 710, antenna tuner, Kiss ground and Gam antenna down to the boat. I placed the radio where it needs to go. The tuner has to be within 4 feet of the radio due to wire and cable lengths, now after this is all hooked up and my antenna is on the backstay, I am 10 to 15 feet short of antenna wire that has to be connected to the anteena tuner. Has anyone ever added cable length to the original antenna cable to make it reach to a antenna tuner. I think it is GP 15,

If you are talking about the coaxial link between radio and tuner, yes you can.
It won't affect tuning. Just use a good quality cable.
Hint: Radioshack is NOT the place to buy it.
There are lots of online places to get good quality coax.
Do a search for Amateur or HAM radio suppliers.

No I am about 10 to 15 feet short from the antenna to the anteena tuner

The antenna tuner should be placed as close to the Gam antenna as possible. (I assume it's attached to the backstay in your case). You then use GTO-15 wire to connect the tuner to the antenna.

You can use ANY LENGTH of coax cable between the radio and the tuner. You should NOT locate the tuner near the radio because of "cable lengths". Use a longer coax cable, either RG-8X or RG-213.

Be sure the coax is properly terminated, i.e., that the PL-259 UHF connectors are put onto the coax correctly, with no shorts or opens.
