RD-5G30 4.9 - 5.8 GHz 26 - 30 dBi RAD-RD2
The 5 GHz frequency band is free to use, worldwide, offers
plentiful spectrum, and works well for long-distance links.
However, 5 GHz signals have more difficulty passing through
obstacles than lower-frequency signals.
The 4.9 GHz frequency band typically requires a license and is
reserved for public safety applications.
