These GPS antennas offer an alternative and secure installation to a
traditional mag mount. With proper positioning in or on a vehicle,
they enhance the performance of the GPS modem.
GPS performance is 26 dB, with 5 dBi antenna gain. The GPS circuitry
has a low 2.0 dB max noise figure with excellent filter characteristics.
Power (2.7 to 5 VDC) and signal is applied through the same cabling
directly to the GPS antenna.
The IW-1575 Glass Mount GPS antenna places the GPS element
directly against the glass of the vehicle, oriented up towards the
satellites. The cable exits near the top side allowing direct entry into
a vehicle headliner. The IW-1575 is designed to be mounted on the
interior of the window only.
The SM-1575 hole mount antenna uses a 5/8" feed thru (16 mm) for
securing to the vehicle. Access to the underside of the body surface
is required to complete the installation. The antennas are enclosed
in a weatherproof ASA radome, and supplied with all hardware and
sealing gasket. The SM-1575 radome is 2.5" in diameter (64 mm)
and very low profile. The SM-1575 radomes are available in white or
black.
