HIGH GAIN HELICAL ANTENNA

Design Features: The AH-405 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. The AH-405 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-405 Helical Antenna is supplied with a specially designed mounting arrangement to hold the antenna at back end by using two stainless steel mounting brackets to withstand the higher wind rating. Optional: A mounting arrangement to support the antenna from front end can also fixed to handle the high wind pressure created by high speed trains. Both LHCP and RHCP models are available.
The part number for LHCP version is AH-405-LHCP and AH-405-RHCP is for RHCP version.
Constructions: The AH-405, like all our AH series helical antennas, utilizes right hand circular polarization to minimize the effects of multipath interference. The AH-405 Helical Antenna is heavy duty, 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. Optional: Two drain holes can be provided at the bottom surface of helical antenna enclosure.
