Wi-Sys Communications Inc., based in Ottawa, Ontario, Canada, has launched the WS1551QF L-band + GPS (L1) Quadrifilar Helical Antenna.

An active right-hand circularly polarized, quadrifilar helical antenna, the WS1551QF provides an omni-directional, cardoid radiation pattern, with peak gain optimized at elevation angles between 0° and 40°. The wideband antenna covers both the L-band downlink frequency band (1525 to 1560 MHz) and the GPS (L1) frequency band (1574 to 1576 MHz).

The antenna features a precisely tuned quadrifilar antenna element, 15KV ESD circuit protection, a high gain two-stage low noise amplifier (LNA), and a ceramic filter housed in a weather-proof, industrial grade enclosure with a bulkhead TNC jack connector.
