Is it worth it? i dont want to melt antennas and such and figured 50watts would give say a cobra 25/29 (something of that caliber radio) the extra push it needs. It looks simple enough with one switch.
What does the pre-amp switch on the higher end models mean? i can figure out on-off, and low-hi-med switches but that one throws me off.

Thanks

Pre amp gives your receive a little boost...ususally you can only run them at night since all they do in the day is amplify static.

An 80 huh?? I don't think you will be melting any antennas with that, but it will get you heard...you should be about equal to a "big" radio.

thats all i want to to. I dont care to own the radio waves, i just want to be heard. If i did leave the amp on i wouldnt want to hurt someones radio next to me.

Thanks

You wont melt an antenna with that thing unless its a really really crappy one, most antennas can take 500 watts or more. At that low of a wattage it wont do a whole lot but it will give you an extra push. the only thing about an amp is you will have to have your SWR's as low as possible, so everything will have to be as close to perfect as possible. A Pre-amp is an amplifier for your recieve. If you where really close to someone else like within 20 feet or so you might damage there radio, its probobly not likely with that amp, but if you run around 1000 watts and your close to someone else it will screw there radio over. If you have any more questions the folks over on http://www.cbradioforum.com/ can answer just about any questions you have.

How do i SWR a radio with just RF gain, swuelch, and a volume knob and a non tunable antenna? i dont know whats there to tune? I can get the SWR thingamagij at radio shack right? I know it wont melt antennas, that was the pint im trying to make, i dont wanting something that powerful.

If you dont have an SWR meter you would have to find someone with an in line SWR thingamajig and borrow it or buy one, if you buy one get a quality one not a cheap one, they run around $20-$30, if you do buy an amp you would be better off buying an SWR meter and leaveing it in line in so you will know if anything hammpens to the antenna or the amp, so you dont damage the radio or amp. and you would need a 3 foot "jumper" coax from the radio to the meter. From what I read on another thread you posted you have fiberglass antennas, to tune those kind of antennas you have to pull off the little cap and slowly (about a 1/8 of an inch at a time) cut down your antennas until it reads the correct SWR. its probobly going to be more difficult to tune duals than it would a single antenna but it can be done.

i borrowed that texas star i was talking about earlier and had no problems with it. 100 watts was some fun talking to guys 20 miles away like they were right next to me. I think im going the route of a 100+ with a low, med, high switch on them.

When i had the amp on with my truck off, it picked up alot of static apposed to with the amp off and CB on? Could someone explain?

Might have had a Pre-Amp built in?? That's what it sounds like...100 watts is fun...imagine 500+.

I have a Connex 250 that I paid 165.00 for brand new.

I by no means am an expert at CBs, but I have heard that the CB and linear need to be, the term I hear alot, married. Meaning you need to take both to a CB shop and have them set-up to work together, and while your at it, get the CB shop to set your SWRs.

Another bit of info I heard is that the longer coax, the better transmitt/recieve will be. Preferably an 18 ft coax.

Others will probably elaborate better here, good luck.

hahaha...100watts??....500watts?? you should hear the 2000kw in my dually
