The maximum range can vary depending on your environment, best distances are generally reached under optimal conditions (e.g. open line of sight). More realistic is to assume a shorter range, because houses, trees, and other obstacles can reduce the signal quality significantly. If you are located in the US, you can benefit from a slightly higher output power of up to 2 watts. However, in Europe PMR446 radios are not allowed to have a replaceable antenna, and can only transmit at a lower output power of 0.5 watts. Because of this, it is perfectly normal that these radios perform best in close-range communication. At first, a short-range may seem like a disadvantage, but if you think about it, it also has advantages. In a city with many users, simultaneous transmissions on the same channel, are less likely if the radios only have a short-range. The benefit, users are not constantly bothering each other on one of the 8-16 available PMR frequencies. Also, the low output power extends battery life, and you can use the radios longer while consuming less power. Also, if your radio would transmit over longer distances, more people could listen in, which is also avoided by the weak transmission power. Because a potential eavesdropper would always have to be close enough to receive the signal. In my test, the communication quality was ok, I think it is best to dry the radio after exposing it to water because otherwise, the speaker won’t have the full volume. Also, I noticed that I had to get a bit closer to the microphone that what I am used to with other non-waterproof radios. / Affiliate Links: As an Amazon Associate I earn from qualifying purchases. / // There is an agreement/cooperation in this video.
