Retevis longer range testing. PMR 446 MHz legal radios

Описание к видео Retevis longer range testing. PMR 446 MHz legal radios

Testing the Retevis RT45 & RB628 446MHz PMR radios to their MAX range in a built up area. The receive radio is in the house which will reduce range. This is a typical range you can expect in a heavy built up area from a fully 100% legal 0.5w PMR radio.
