Spectracom offers model 8230 for certain products with embedded GPS/GNSS receivers. Model 8230AJ also includes
horizon-blocking anti-jam technology. Each antenna is shipped with an L-bracket and clamps for affixing the antenna to an
appropriate structure. Various accessories are offered to facilitate installation of the antenna.
NOTE: A rugged antenna mount, post mounting kit, weather-proofing kit and free-standing base are sold separately.
Contact Spectracom for details and to order these a cc essories for your antenna.
Model 8230 and 8230AJ are active GPS/GNSS antennas covering the following bands:
• GPS L1
• GLONASS L1
• BeiDou B1
• Galileo E1, and
• QZSS L1.
The active antenna circuitry provides 40dB of gain and requires 2.5 to 16 V
21 milliamps (provided by a Spectracom recei ver over the antenna cable) to operate.

Installing the Antenna
The GPS/GNSS antenna must be installed outdoors with an unobstructed view of the sky (to 20° elevation from the
horizon). An unobstructed line of sight to the sky allows the antenna to locate and track the maximum number of satellites
throughout the day. Installations with obstructed views may still prove functional, but the equipment may experience
reduced reception quality or be unable to simultaneously track the maximum number of satellites. Make sure the antenna
is installed somewhere that it will not be buried in loose or drifting snow, or obstructed
by growing foliage. Whenever possible, avoid placing the GPS/GNSS antenna in close
proximity to broadcast antennas. See Spectracom’s Technical Note for detailed
information on antenna installation.
When using the included L-bracket, remove the
double panel nuts, insert the connector end into
the 19 mm (0.75”) through hole and replace
and tighten the nuts. Connect the L-bracket to a
post, pole, vent pipe, or other suitable location
via hose clamps. Then connect the antenna to
the antenna cable via type N connectors. In wet
weather locations, it is recommended to wrap
the connection in weather-proofing tape.
Spectracom offers a weather-proofing kit for
this purpose.
A rugged antenna mount is available
separately as model ANT-KT (see picture on
the left). It is designed to mount to a vertical
or horizontal pipe, or to a flat surface.

Antenna Cable and Accessories
When using a Model 8230 or 8230AJ GNSS outdoor antenna, Spectracom recommends using low loss type cable for the
antenna cable such as LMR-400 (or equivalent). To simplify the installation process, Spectracom offers cable assemblies
terminated with Type N Male connectors. S tandard lengths are 25, 50, 100, 150 and 200 feet.
If the antenna cable is purchased locally, select coax suitable for outdoor use. A surge protection device in the antenna
line is recommended to protect the GPS/GNSS receiver and connected devices from lightning damage. Spectracom
offers Surge Suppressors to shunt potentially dam aging voltages on the antenna coax to ground.
Cable Length
With low loss LMR 400 equivalent antenna cable, the maximum recommended antenna cable length is 125 meters or 400
feet. Installations requiring longer distances can be achieved with an inline amplifier. See Spectracom’s Technical Note for
detailed information on cables and allowabl e cable lengths.
