Questions & Answers

What advantage does one gain by using the "Upgrade" antennae SMA-M 40CM versus the factory supplied unit on the Retevis handheld radio?
A longer antenna made for the operating band offers two advantages.
1. It will help the radio hear weaker signals, thus increasing the range that the radio can recieve.
2. As the antenna offers greater gain, it will "amplifiy" the outgoing singal allowing it to go farther.
