RFS TrunkLine Antennas are designed for microwave backbone networks, long distance, high capacity links
A choice between tested and validated ultra-high (ETSI EN 302 217 Class 3 and FCC Class A) electrical performance or high (ETSI Class 2 and FCC Class B) performance
Sizes ranging from 1.8 m (6 ft) to 4.6 m (15 ft)
Single- and dual-polarized models with the ability to upgrade from single to dual polarization and change frequencies in the field in most cases


  • 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
