 Model AH-1013-12 1050-1300 MHz 12 dBic Gain 
 

HIGH GAIN HELICAL ANTENNA

Design Features: The AH-1013-12 uses extended stubs to provide the greater gain while maintaining the wider beam-width and designed to provide wideband directional transmission/reception of radio signals from 1050-1300 MHz bands including. This high-gain low-profile antennas use Circular Polarization Antenna Technology - which delivers better penetration through obstruction and interference. The AH-1013-12 helical antenna is highly suitable to provide the uninterrupted communications in the tunnels. 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-1013-12 Helical Antenna is supplied with a specially designed mounting arrangement to hold the antenna at back end by using stainless steel mounting brackets to withstand the higher wind rating. The AH-1013-12 helical antenna is supplied with a specially designed mounting arrangement for steering the antenna in both planes, 360 degrees in Azimuth and 90 degrees in Elevation for terrestrial and satellite link. Both LHCP and RHCP models are available. The part number for LHCP version is AH-1013-12-LHCP and AH-1013-12-RHCP is for RHCP version.
Constructions: The AH-1013-12, like all our AH series helical antennas, utilizes right hand circular polarization to minimize the effects of multipath interference. The AH-1013-12 Helical Antenna is heavy duty, broadband and rugged helical antennas, supplied with fiberglass radome to protect the antenna from environment. The radiating element of high power helical antenna is made of high quality high strength enameled coated copper wire and winding is secure alongside wall of fiber glass enclosure to keep the helical winding/radiating element to its appropriate location to prevent RF inter-modulation.
