    im not real familiar with amps so I’m turning to y’all. I have a galaxy 98 does about 265-300 depends on who tests it. What would be a good size amp to pair it with to use it as driver?

    Are you really serious? You are getting 265 watts to 300 watts and you want to add an amp? I have never run more than 100 watts and make all the contacts I want.

    A very big one.

    To get a decent increase in signal from what you are running now would at the very least require a 16 pill.
    I am going to ASSume that this will be in a mobile setup.

    Lots of money and all of the assorted stuff that goes along with it just to run it.
    Big Amps, Big wires, big headaches.

    16 pill for the mobile or a 3cx3000 for the base.

    Consider that most amplifiers have a gain factor that multiplies the input wattage by a factor of ten or more.

    And some amplifiers multiply the drive level by a factor of twenty-to-one or more.

    So, an amplifier that puts out between 3000 and 6000 Watts is getting serious. The coax and the antenna will both have to be stout enough to run at that level.

    The DC power needed to run an amplifier this size will require more than the vehicle's stock alternator can provide.

    IMHO a radio the size of yours is pretty much in a sweet spot, where most antennas will handle the power and normal RG-8X/mini-8 coax is big enough. Running the DC power directly to the battery is about all you need to do unless the alternator is really small.

    And if you just have the irresistible need to get larger, it's only money.

    Maybe he wants to make more contacts than you do.

    There’s no reason he can’t drop the power on the radio to drive something that’s not 6000w.

    Specs show this radio as 10-50 watt carrier and 200w PEP.

    In the end, it’s all just a matter of whether or not it’s worth it.

    With only 100 watts running from a mobile on a hill top with a "Hamstick" I talked to Mumbai India. I have no idea how far that is, but iI think in excess of10,000 miles.

    Sure, and you may not have even needed the 100 watts. People like power, though. It gets very expensive when you need to start adding alternators and power cables that cost several dollars per foot.
