Works well with an external antenna on my van. The rubber ducky antenna doesn't have a very good signal because it's in the car. And the radio puts out 4W when plugged in, but it's not as powerful when running on battery (sometimes). It depends on what kind of batteries you use and how much charge you have left in them. The display on the radio shows you how many watts you are spending. The maximum output power of this radio is 4W, which is standard on all legal CB radios. It is a smaller and easier to use alternative to the CB overhead radio system. Don't think your radio is down just because you can't hear anything on the CB radio because sometimes not many people use the radio so not much to do here anyway. Also make sure the squelch is not too high. NOAA weather works well with both antennas. If you have an extra cable for an external antenna, do not twist it into a loop. Fold it into an eight. Looping an extra chord in a circle can ruin the incoming signal. I put 9 NI-MH AA EBL Ni-MH rechargeable batteries in the radio and was surprised at how long they last. They usually last a few months before needing to be recharged. However, most of the time I can still just use the network connected radio. The magnetic antenna attaches very securely to the car's metal roof, so even with a slight curvature of the roof, you don't have to worry about the antenna being blown off at high speeds. I would like the cable from the antenna to be a few meters longer. The radio is well made and the plastic feels relatively solid. The buttons are easy to feel and press, and the backlit button lets you see the screen at night. All in all I am very happy with this radio. This was exactly what I wanted and is a great alternative to save money and time compared to installing a CB radio and antenna and then plugging it together and buying an antenna tuner to tune the antenna, assuming you know , how it goes. and, well, you get the idea. This is VERY IMPORTANT by the way; It is FORBIDDEN to start the car with the radio connected and turned on! A sudden voltage drop can damage the radio. I almost broke mine in the process. To fix this I unplugged the radio, removed the batteries and left it on for about 30 seconds. (Standard computer repair procedure). Luckily I was able to get the radio working again! If you want your radio to continue broadcasting, you can purchase a long tunable antenna and tune it to your radio. There's an instruction video on YouTube if you're interested. So buy yourself a CB radio and discover a whole new world on the highway, or you can use it to talk to your spotter off-road anyway.
