    What guage wire, what amp Anderson Powerpole and what amp in-line fuse for battery wire do I need for my mobile installation? Radio is equipped with wires and fuses. Running power from battery to radio wires. First-time mobile user...

    What is the current draw of the radio? The other answers are based on this.

    You can get an idea of the answer based on the wiring and fuses that came with the radio. What gauge are the wires, and what are the fuse ratings?

    The radio manual shows Current Consumption RX: 0.5 A and TX: 8.5 A. The red and black wires of the radio are fused with 15 A fuses. No markings on the wires to show gauge but I guessing they are 20 AWG? (Is that the right term). The radio output power is max 50 Watts. Is that what you were asking to know?

    The manufacturer of the radio would have already taken all of this into account. If you use the wire and fuses provided with the radio you should be fine.

    I installed a separate DC SUBPANEL for my Ham Radio units using a heavy gauge hot cable coming from the battery bank...


    This allows me good solid fused screw terminals for Ham Radio items... All installed in a convenient spot inside m POPUP trailer...

    I like using these covered fuse blocks as well...
    Most of we Ham radio guys are forever changing thing around haha... This is my floor plan layout showing location of several items...


    I am usually setup for several days where I am camping off-road somewhere... Like to put up my off-center Wire Antenna up into air with ends thrown up into the trees on both sides. Sort of an Inverted VEE looking thing... Loved my 80/40 bands back in the day...

    Haven't been out in a few years now but bet I could get on the air rather quickly...
