SC21 Antennas
Sepura offers a range of antennas for the SC21 hand-held radio to suit a wide variety of deployments. Antennas are colour coded on the base to indicate frequency band.
Nominal gain figures shown in the table are measured in free space at resonance. These figures will degrade when used close to the body.
General characteristics
Nominal impedance: 50Ω
