It depends on lots of factors....

First, the output power of your radio. Many claim 5watts output, but when measured on an accurate SWR / power meter, they are usually closer to 4 watts. Also, they usually output full power only with external power supply, not internal batteries.

Second, the antenna. If you are using a "rubber duck" helical, range will be at its minimum. If it has a quarter (1/4) wave telescopic whip (about 2 meters!) then that would be better.
If it has a socket for external antennas, then a (1/4) quarter wave car mag mount on something metal and 1/4 wave in radius this would be pretty good, especially if mounted above any local restrictions like buildings and walls.
The ultimate would be a half 1/2 wave antenna, mounted at least 1/2 wave (5 meters!) above ground, on a scaffoling pole or similar at least 1/2 wave long (5 meters).

The station you are speaking to also has a lot to do with range, if they have a good station, then range will be better.

With 5 watts, at the right time of day, with the right antenna, and under the right conditions, CB can reach across the globe! Yes really.

You need to post more info on the type of set up you have.

Hope this helps

Handheld Radio Shack CB radio TRC-230 I can hear people but no one can hear me


First, lets make sure that the unit does transmit. Get a power meter and see how much power it transmits. If no power is being radiated, you need to have a technician check out the unit.
If you have power then pick a less crowded time to test out if anyone can hear you. Other people with more powerful equipments can only be a problem when you are transmitting on the same channel and both of you happen to transmit at the same time all the time. Chances are remote that this is your problem. Good luck. es

How can i get the frequency 130.00mhz - 150.00mhz from 75-822?


No. CB radios operate in the 27 MHz range and cannot be modified for out of band operation.

Does not seem to have very limited range


Hi, my name is John. Welcome to FixYa. All of the handheld,s have very short range. Try to extend the antenna as far as it will go and depending on your location, it should get out a little further..good luck. Thanks for choosing FixYa... John

Dose it work good like i live in a prtty good nabor hood dose it get good distance will it conect withe other bigger cb radios


Typically, this type of handheld has a useful range of approximately 1-2 miles. This distance will be increased with other radios being mobiles and base stations. Distances of 5 miles is possible if the other person has a good base station antenna. I would not expect much from the stock rubber ducky antenna.

Hand held cb


installed ones, are you refering to base stations? these rigs are more powerful because of the higher wattage outputs and stable installed aerials. :) your handheld can put out as much as 5 watts of power.
