Cable company hooked up our internet modem using 18 gauge coax.

I want to run an extension to move modem.

I have a bunch of 14 gauge.

I always thought the lower the no. the thicker the wire and the better.

however the cable co. wire is thicker overall and before i crawl up under the house i want to be sure im not **** it up.

Any advice would be greatly appreciated.

    Probably just thicker insulation. Shouldn't matter if you use your 14.

    Edit: Wait. Up under the house? Are these wires running outside? Then, insulation may play a larger role.

    RG-59 usually has a 22awg center conductor, where RG-6 has an 18awg center conductor. Never heard of 14awg coaxial cable...?

    That's what i was thinking.. you don't see coax measured with gauge...usually it's the type RG-**** and based on that you get a size/rating.

    You have a bunch of 14ga what? If indeed it is coax I doubt it is 75ohm. Go buy some of the right wire.

    you cant take a step around here without learning something.

    thanks for all the replys, i always thought all the thick black stuff was coax.

    also the resistance was something i never thought about in regards to video or data transfer.

    again thank you.
