SC20/SC23 Antennas

The SC20 and SC23 hand portables are available with a wide range of antennas. These are selected depending on the operational frequency band, the carrying position of the hand-portable and the level of RF coverage of the network. Antennas are colour coded to indicate frequency band.

The extended compressed helical and the quarter wave whip antenna have similar performance characteristics, offering higher gain and improved coverage compared to the compressed helical and can be used when network coverage is restricted.

Technical specifications

Nominal impedance 50Ω

VSWR at resonance ≤1.5:1

Connector type SMA male

Operational temperature range -20ºC to +55ºC (useable range -30ºC to +75ºC)

Please note:

The UHF SC20/SC23 antennas are the same as those used with the STP Series hand portables.

Nominal gain figures shown above are measured in free space at resonance. These figures will degrade when used close to the body.
