Antennas are colour coded 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
VSWR at resonance ≤1.5:1
Connector type: proprietary
Operational temperature range: -20ºC to +55ºC (useable range -30ºC to +75ºC)
All antennas are supplied in packs of 10 of the same type.
