    Hi all I just got my first 10 meter radio on my birthday the other day (my first HF actually!) and was wondering what coax would be best to run from the radio to the balun. The length would be 50 feet. I don't want to drop a fortune into the cable either. RG/U? RG8X?




    Thanks,

    I assume your running low power, RG58 is fine. I assume your using some type of resonant antenna, highly recommend a beam. There small, easy to home brew and will give much better results over a dipole, ground plane or vertical.

    I use RG 213 works fine and if, you eventually go high power no replacement worries.

    Rg8x or rg8. You can still use it when you upgrade your gear

    10 meters is low loss. Just about anything will work. Have fun.

    Sometimes I use free coax cable.

    Nothing wrong with using cable TV coax as antenna feedline you know.

    Since you are on one band and just getting started I presume, I would make a nice dipole resonant for the center of the band. Install it in an inverted V configuration feed it with 58 or 58x and you'll get results. Keep in mind that we are on the down solar cycle so 10 will be in and out, but you'll still make contact and some will surprise you. Dipole is easy to make, look up the formula on-line. No need for a balun just go straight to the antenna. What kind of rig and how many watts?

    At 100 watts out with an SWR of 1.2:1 the power that reaches your antenna will be 79.8 watts, if you use 50 feet of RG-58.
    If you use 50 Feet of 9913 coax, 92.6 watts will reach your antenna.

    I got a Realistic HTX-100 for my birthday and was gonna make a dipole.

    SSB at relatively low power? RG8X is more than good enough and is cheap and light.
