The S.EFX series of glassfibre dipoles are designed for professional base station and fixed mobile applications. The antennas have been designed with an integral dual purpose mounting bracket, cast in aluminium. The stainless steel fittings enable the antennas to be fixed to the top or side of a vertical pole up to 60mm diameter. The centre fed dipole is fed via coaxial cable, giving a stable radiation pattern over a wide operating band. All S.EFX series are d.c. grounded. A VSWR of 1.5:1 is achieved over a bandwidth of ±6% of centre frequency.
