Model AH-280 240-325MHz 12 dBic Gain Download Datasheet Download Manual Post Enquiry

High Gain Helical Antenna

Design Features: The AH-280 uses extended stubs to provide the greater gain while maintaining the wider beam-width. This high-gain low-profile antennas 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 AH series helical antennas are smaller than conventional yagi antenna. The AH-280 Helical Antenna is 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. Elevation tracking can be done if antenna is mounted on horizontal mast/pole. Broadband design feature of antenna makes it highly suitable for SATCOM application as SATCOM ground station antenna without having the requirement of multiple antennas.
Constructions: The AH-280,, like all our AH series helical antennas, 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 AH-280 Helical Antenna is light weight, broadband and rugged helical antennas, supplied with high strength 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. The antenna is designed as per MIL-STD-810G standards.
Array Formation: For higher gain requirement, the Helical antenna can be supplied in DUAL stacked or QUAD stacked arrays formation with suitable power splitter/combiner cable harness. Customized color and customized mounting can also be supplied on request.
