 Model AH-1117-11 1100-1700 MHz 11 dBic Gain 


Design Features: The AH-1117-11 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 1100-1700 MHz bands including GPS L1, GPS L2, L5, L6 bands. This low-profile antennas use Circular Polarization Antenna Technology - which delivers better penetration through obstruction and interference. Both Right Hand Circular Polarized (RHCP) and Left Hand Circular Polarized (LHCP) helical antenna models are available. 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-1117-11 Helical Antenna is supplied with a specially designed mounting arrangement for steering the antenna over 360 Degrees in Azimuth direction and 90 degrees in elevation.

Constructions:The AH-1117-11, like all our AH series helical antennas, utilizes circular polarization to minimize the effects of multipath interference. The AH-1117-11 Helical Antenna is light weight, broadband and rugged helical antennas, supplied with ABS 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. For higher gain requirement, the Helical antenna can be supplied in DUAL stacked or QUAD stacked arrays with suitable power splitter/combiner cable harness.
