Antenna
This new series compliment's our 800/900 MHz band
product line. The body/surface mount antennas can be
mounted to any vehicle, container or bulkhead. The
rugged style is excellent for industrial applications, yet
attractive for consumer use.
Antenna performance on the SM3 series is 3 dBd (5
dBi), and requires no ground plane for performance. The
antenna can even be mounted on fiberglass or plastic
housing and meet all specifications. It is outfitted with a
black polycarbonate radome. It requires a 3/4" hole for
mounting. It is fitted with a weatherproof gasket for
complete sealing. It is supplied with 15 feet of RG-58
cable, and TNC connector as standard. This series can
also be outfitted with a GPS module for dual band GPS
trakcing applications.
The low profile SM Series is a unity gain device and
requires a ground plane for best performance. The
radome is durable polycarbonate, available in white,
grey or black. It uses a gasket for weathersealing.
Outfitted with 15 feet of RG-58 and male TNC, it requires
a 5/8" hole for mounting. This series can also be outfit-
ted with a GPS module for mobile tracking.
