The AHQ-1117-21 extended long range ground control station helical antenna 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 bands. The AHQ-1117-21 high gain helical antenna is highly suitable to provide the uninterrupted communications and Jamming for all GPS bands. AHQ-1117-21 is military grade high gain helical antenna provides superior performance as compare to significantly larger and more expensive products. Our AH series high gain helical antennas are smaller than conventional yagi antenna.

Military Standards AHQ-1117-21 High Gain extended long range ground control station 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 AHQ-1117-21 high gain 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 helical antenna is AHQ-1117-21-LHCP and AHQ-1117-21-RHCP is for RHCP version of high gain helical antenna. AHQ-1117-21 high gain helical antenna is highhly suitable for UAV anti drone application without having the requirement of multiple antenna. Only one antenna AHQ-1117-21 helical antenna is capable of jamming all the GPS band saving the cost and space of infrastructurs.

Antenna Experts AHQ-1117-21, like all our AH series high gain extended long range helical antennas, utilizes right hand circular polarization to minimize the effects of multipath interference. The AHQ-1117-21 High Gain 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 gain 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/hosing/radome to keep the helical winding/radiating element to its appropriate location to prevent RF inter-modulation. The AHQ-1117-21 high gain helical antenna is designed as per MIL-STD-810G standards.

Quad stacked AHQ-1117-21 circular polarized high gain extended long range ground control station helical antenna is completely protected within a high-tech ruggedized radome which is made of high strength fiber glass encosure to ensure survivability in the worst environments conditions The heavy duty fiber glass enclosure has excellent transparency for RF signals and enough strength to withstand more than specified wind loads. Cylindrical enclosure is used for low wind loading and for minimal effect of ice formation on the high power high gain broad band antenna operation as well as providing an aesthetically pleasing appearance. The extended long range helical antenna is supplied with olive green MIL color finish. Other customized housing/radome color can also be supplied on request.

Our AHQ-1117-21 directional high gain extended long range ground control station helical antennas are supplied with two-axis steering system (tracking mechanism to rotate the UAVs Ground Station Antennas manually in azimuth and elevation plane). A less complex but compact multi-sector antenna array provides intermediate range coverage for communicating with a UAV. This type of arrangement can be used for quick deployment and tactical applications.

Both, Right Hand Circular Polarized High Gain Helical Antenna and Left Hand Circular Polarized High Gain Helical antenna can be supplied. For higher gain requirement, the Helical antenna can be supplied in DUAL stacked or QUAD stacked arrays. The listed antennas are basic and generic models. Antenna Experts would be pleased to know more about your customized gain and frequency band.
