We shall answer it affirmatively for you today. We have had this question come to us time and again. You will have to replace the whole thing or get it repaired based on the particular problem. However, if your hardware is old and rusted, even a booster will not help you. The most common of the three problems is a weak signal, and you can solve it with ease by getting a good car antenna booster. Let’s begin by understanding the most common reasons behind this problem. In this article, we will do our best to help you out. Sadly, you won’t ever be able to figure out what the exact reason is, and so, coming up with a permanent solution can be tricky. This usually happens due to interference, but there are other reasons as well. It is very annoying when the signal is very weak, and you can’t listen to your favorite radio channel. ![]() If you change antennas frequently, consider using a low profile BNC adapter where the base sits on top of the radio and isn't completely dependent on the SMA jack for all of its mechanical strength.The most popular pass time while driving a car is listening to the radio. If you use one antenna and rarely disconnect it you'll be fine. Important General Tip: The pin inside the SMA antenna connector will eventually break! The connector is rated by design for approximately 500 connection cycles. 2 meters will give you longer distance propagation in open areas. 2 meters and 70 cm perform differently and have different advantages depending upon the surrounding terrain.Height and Line of Sight are your friend.Use a power supply to make sure you a getting full output power.Use 70 cm where possible instead of 2 meters if it's appropriate for your area.A magnetic mount antenna for a car placed on a window air conditioner works well. There are many simple choices that don't involve trying to put a large antenna on a roof. The shorter 70cm waves have a much easier time getting through window openings than the longer 2 meter waves. Get your antenna outside, especially if you are using 2 meters.Power the radio from the car to ensure you are getting the full output power your radio is capable of. ![]() Make sure you've got enough metal in the roof and that the antenna is as close to the center of the roof as you can. A magnetic mount antenna can be a good non-permanent solution. The body of the car will absorb much of the signal. battery voltage have been published for the Baofeng and the similar Wouxun online and in the Yahoo groups. The lower the voltage from your battery, the less your power output (in watts) will be. Your radio is only putting out the rated power when it is getting the design voltage. Make sure your battery is fully charged.Bring the radio up to your mouth when transmitting. Get the radio off your belt! If you are using the headset with the radio attached to your belt, your body is absorbing much of the signal.The rat tail suggestions are good ones, which are providing a better ground plane to complete the other half of the antenna. Your body is making up the other half, the ground plane. The standard rubber duck antennas are 1/4 wave, which are half of a 1/2 wave dipole, oriented vertically.While it's inconvenient to carry around, a 14-15 inch "gain" antenna can help in many cases where a 4-8 inch stock duck can't be heard. An antenna that is physically close to the right wave length (1/4 wave, 1/2 wave, or 5/8th wave) on the frequency you want to operate on will perform better (have less signal loss) than a shorter antenna.All of the stock rubber duck antennas tend to be a compromise and not perform very well, but the stock, stiff, short baofeng antenna seems to perform worse than others. The stock Baofeng rubber duck antenna has been shown to be a poor performer. ![]() Answers would also be more relevant if we knew what situation(s) you were coming up short range wise. There have been a number of good answers already, though I think there are a few additional points worth sharing.
