HELI-A0103 is a dual port helical spiral, right-hand circularly polarised antenna designed operating in the 433 - 435 MHz and 900 - 930 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.
