Question: Do i need to buy and antenna for this? Or does it come with one?
Document: good, small, but quiet, could use a better speaker.need to buy a antenna.my first one and loving it so far, just needs a better speaker and reception.
This is a good radio for the cost. I paired this with the Lil Wilson antenna and it is working well. I like that it has a PA mode. The mic is probably the weak link here. But you can buy a nice mic and plug it in to this radio though and you would then have a really nice setup. For the beginner, this is hard to beat. I would recommend but know that you will need to upgrade the mic at some point.
Great set up this is the second one I bought I put this exact one in all my trucks has everything you need and has a inline fuse so it is very nice and a great price
Great little CB radio, does exactly what you need. No scan feature but, I don't think you truly need one. nice build quality and this baby is small so it mounted up just right.
The volume from the built-in speaker is more than adequate in the SUV, and the radio itself takes up so little space and weighs so little that I have many mounting options; at the moment it's on the back of the center console, but should I determine that it might be useful for more than listening, there's space under the dashboard and on the front of the console as well. It's just a really nice little CB for someone who has only occasional need for one.
So I'm new to the world of CB radios but this CB is so simple, I didn't need much instruction on how to use it. It's cheap too. I had it installed in my truck in less than an hour, and the first half of that was deciding where to put it lol. I also get great reception from a fairly long distance, but that might be the whips too. I'm not sure. But anyways, If your looking for a quality, cheap CB this is the one.
this is my first CB and just wanted something basic for my Jeep, just for trail use. so far it's held up great, i get a lot of sand in my Jeep is still working like new. i like the mic better than most other CB radios. volume is plenty, screen is very clear and has the basics. i really like the fact that you can add a PA speaker to it, have yet to buy one though.
You don't need a fancy cb radio, just a good quality cb and a higher end, better quality antenna. You simply can't go cheap with the antenna and transmit good! I matched this cb with a &#34;lil-will&#34; antenna and it transmits very good with crystal clear reception. VERY PLEASED  :-)
Didn't buy this for the CB radio function as I really wouldn't want an antenna on my car. The PA system is what I wanted, and it works great for that. I installed it stealthily in my center console with all the wires feeding through the bottom. The PA function works as expected and is incredibly loud when paired with the PYLE PSP8 5in speaker.
I purchased this CB to replace a much older version to install for a long road trip. You have to decide if your going to wire the power to your car battery, or wire a cigarette lighter adapter on to it, since it comes with just open wires. Not a big deal to wire the plug, I watched a youtube video and got it done in under 10 min. I still need to tune the antenna to the CB, but even without that I have a fair range.
Answer: You need to purchase an antenna, and antenna cable.
