HL-225-400

Design Features: The HL-225-400 UHF Aeronautical Band helical antenna uses extended stubs to provide the greater gain while maintaining the wider beam-width. This high-gain antenna use Circular Polarization Antenna Technology - which delivers better penetration through obstruction and interference. This commercial grade antenna provides superior performance as compare to significantly larger and more expensive products. Our HL-225-400 helical antenna is smaller than conventional yagi antenna. The HL-225-400 Helical Antenna can be supplied with a specially designed mounting arrangement for steering the antenna in both planes, over 360 Degrees in Azimuth and 90 Degrees in Elevation for terrestrial and satellite links.

Constructions: The HL-225-400 UHF aviation band helical antenna, utilizes circular polarization to minimize the effects of multipath interference. Both Right Hand Circular Polarized (RHCP) and Left Hand Circular Polarized (LHCP) helical antenna models are available. The HL-225-400 UHF Aero Band Helical Antenna is light weight, broadband and rugged helical antennas, supplied with fiberglass radome to protect the antenna from environment. Cylindrical enclosure is used for low wind loading and for minimal effect of ice formation on the helical antenna operation as well as providing an aesthetically pleasing appearance.

Array Formation: For higher gain requirement, the Helical antenna can be supplied in DUAL stacked or QUAD stacked arrays with suitable power splitter/combiner cable harness.
