TrunkLine Antenna, High Performance, Single Polarized, 4 ft

Rev : B | Rev date : 03 Jan 2023

RFS Microwave Antennas are designed for microwave systems in all common frequency ranges from 4 GHz to 15 GHz. Different options of survival windspeeds are available. This allows the use of antennas in areas where extreme wind conditions are normal. The antennas utilise a conventional feed system and are available in three performance classes offering complete flexibility when designing a network.High Performance antennas are ideally suited for systems where a good level of side lobe suppression is required. These antennas are required for use in networks where there is a high interference potential.Antennas are available in 2 ft (0.6m) to 12 ft (3.7m) diameters. The High Performance antennas are available in dual polarised (DAX) as well as in single polarised versions (DA). All antennas include a radome which is specially shaped (2 ft) or flexible (4 to 12 ft) to minimise its impact on the antenna?s electrical characteristics.


  • Field-proven reliability and long life
  • Support for winds up to 200 km/h (125 mph) with high-wind versions that support winds up to 252 km/h (155 mph) and an optional sway bar for added assurance in case mistakes are made during installation
  • A single-piece configuration and compact packaging to reduce transportation costs
  • Frequencies ranging from 4 GHz to 15 GHz with support for two wideband frequency ranges (5.725-6.875 and 7.125-8.5 GHz) to reduce antenna requirements and simplify logistics
