    Hello all. I'm looking to get a small amp for my CB radio. Nothing too crazy, just need a couple extra watts. Helps when I really need some info during unexpected traffic jams.

    I already have one picked out upon good recommendations but that only helps for my TX. I still would like to increase my RX. Can I install both a preamp (for RX) and a linear amp (for TX) at the same time?

    How does the wiring design work for something like that? Which connects first before the antenna? Is it something like connecting the coax as follows:

    CB -> preamp -> linear amp -> antenna


    Any input would be great.

    You should spend the money on a tune up on the radio for tx and good antennas properly set up for your rx.

    If you do go the amp route, Palomars and Texas Stars already have a pre-amp in built in.
    In that case of going just an amp, on the back of the amp it will tell were to connect the coax. (radio in, radio out)

    My problem is combining a linear amp and a preamp which one would go first.

    Depends on whether or not your preamp can switch the power from your amp.

    Preamps work better the closer they are to the antenna, but not if the amp is going to blow it out.

    Personally, I would forget about the receive amp. Most anything I have heard just increases all noise. Just get a radio that is tuned properly and leave it at that. Now if you want to play the distance game then look at something in the 350+ watt range. Just my opinion.

    Yeah I think I'm going to ditch the preamp. I figured for home use it might help if my dipole antenna was indoors. But for now I'm just sticking to a linear amp. I got one around the 30-40W just to start with something small. I don't need to go crazy far I just want to be clear at least near by.

    At the time, I am just running an export Connex that does way more then needed for local comunications. Most the time I have it turned down to about 30 watts average and doing about 150+ peak. It is usually more then enough to get my point across locally. Now if I want to hit the walls then I can turn it up and hit either the sand pile or shaky ground from up here in the Dakotas.

    Some amps have built in pre amps. however as pointed out most just introduce more white noise.

    With that said, what kind of antenna do you have? That really makes all the difference in how well you can receive, and transmit.
