Wi-Sys Communications offers its 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).
