Extend the Range of Your Communication
Receive Hard to Hear Signals and Transmit Further
Most Nagoya antennas will increase your radio's transmitting gain compared to their factory antenna.
In most cases: the longer the antenna is the better the antenna is capable of boosting weak frequencies and receiving difficult to hear stations. Shorter antennas offer more portability and convenience, while longer antennas generally perform better.
