QHA-5060

Design Features : QHA-5060 broadband omni-directional RHCP quadrifilar helix or LHCP quadrifilar helix antenna is rugged all weather model, enclosed in a ABS radome, uses high class copper alloy and does not require any field tuning or adjustments. The compact size of LHCP or RHCP omni-directional quadrifilar helix antenna allows easy handling, shipping and highly suitable for receiving, transmitting, scanning, monitoring, surveillance and jamming applications without having the requirement of multiple antennas. The antenna is also highly suitable for Ground to Air communication/jamming application due to its wide elevation beamwidth with omni-directional properties. The antenna is supplied with N-male termination to mount it directly on equipment/modem. It can also be mounted on chassis/thru hole vehicle/UAV/Drone using N-Female to N-Female convertor supplied with antenna. Other type of mounting hardware / configuration can be supplied on request.

Constructions :The QHA-5060 LHCP or RHCP quadrifilar helix antenna is consisting of two (pair) vertical loop radiating elements at right angles to each other, twisted into a helix turns vertically and enclosed in ABS radome. The special “Teflon Dielectric Transmission Line” technique is used to handle high power handling capacity allowing smooth VSWR and typical 2dBi. gain over the entire 5000-6000 MHz. frequency band. The UV resistant ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. The QHA antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. Cylindrical shell/enclosure is used for low wind loading and for minimal effect of ice formation on the antenna operation as well as providing an aesthetically pleasing appearance
