Dual port Helical Antenna


HELI-A0105 is a dual port helical spiral, right-hand circularly polarised antenna designed operating in the 2400 - 2500 MHz and 5100 - 6000 MHz bands. The antenna provides broad beam coverage without nulls or reduction in performance. The antenna features a low VSWR and high gain over both operating bands with a light weight, yet robust radome to protect the radiator.
