The WS3978-HR High Gain “No Interference” Permanent Mount GPS Antenna provides 40 dBs of
gain and very high out-of-band rejection performance. It features a perfectly tuned custom ceramic
patch element for maximum signal reception, ESD circuit protection, a 3 stage LNA circuit and a dual
SAW very high rejection out-of-band filter, enabling the WS3978-HR to provide most reliable and
clear GPS signal reception while minimizing loss-of-lock, even in high RF fields. Available in an all-
plastic, non-corrosive low profile package for vehicle mount or with a cone-shaped radome cover for
fixed installations, the WS3978-HR high gain, high rejection permanent mount GPS antenna is the
optimum choice for applications with high RF fields requiring long cable runs.
