The HELI-A0103 is a dual port helical spiral, right-hand circularly polarised antenna designed for 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 is suitable for use in both high power transmit and communications applications.

The antenna features a low VSWR and high gain over both operating bands with a light weight, yet robust radome to protect the radiator.
