RF power is an indicator of the distance the 2-way radio can transmit and the strength of the signal under unfavorable conditions. In many cases, customers use the 2-way radio for distances not more than one mile. Transmitting sound in such a distance requires less than 1-watt power. You might, however, need more power if you are communicating during unfavorable conditions. Buildings, bad terrain and other things between the parties weakens the signal. Depending on the conditions of your communication area, choose the ones with more power for best and clear sounds.
When talking of battery, we are looking at the voltage, capacity, and type. The battery is among the top features which define 2-way radios. If the battery is not working well, nothing else on the radio will work as expected. Choose a radio with a rechargeable battery which can be recharged as many times as possible. The higher the number of milliamps per hour, they measure the battery capacity, the longer the battery will last.
Weight and Dimensions
Considering the weight of the radio is very important as well. You need something that can be easily carried around. Well, why do we wear watches and not carry clocks? It is the same reason why you should choose an easily portable 2-way radio. A lightweight, rugged radio will be the best choice. Always consider the battery life and antenna as you choose on weight.
The best 2 way radios should have programmable channels and the more the channels, the better. You will have more frequencies and more options to avoid interfaces from other people using the same frequency. This works best in congested areas. The best 2-way radios have a minimum of 12 programmable channels.
The audio output of the 2-way radio is measured in mW. It should be loud enough to hear what the other person is saying even under a lot of noise. A 500 mW is a good option. To generalize everything, the higher the mW, the better the output.
Put into consideration the above factors when purchasing a 2-way radio. The best qualities are more expensive so be ready to part with good cash for the best quality. In addition to that, look for trusted dealers, they will sell you genuine devices with a warranty.
