TurfWeather Weather Station
1. Location Preparation:
a. Determine the best location for the antenna, assuming that the
distance from the antenna to the RF401 base station is equal to, or less
than, the length of the NTN-Lxx antenna cable.
b. Assure that the ground rod is installed into the soil as close to the
location of the Polyphaser as is possible. NOTE: A ground wire (00
gage) is supplied but it may not be long enough for all installations. If
a longer ground cable is required, purchase a continuous length to
meet the site requirement but always use the minimum length
necessary. Do not reduce the gage of this wire if a longer length is
required. An alternate method of earth grounding may be employed
but should be confirmed by a qualified RF technician before use.
c. Mount the Polyphaser within 5 feet of the location of the RF401 base
station on a ground plane, or ground buss bar, inside a weatherproof
enclosure or building. Mounting recommendations are supplied with
the Polyphaser. NOTE: The ground plane or buss bar will also be the
connection point for the earth ground cable to the exterior ground rod,
or interior earth ground connection.
d. Connect the heavy gage (00 gage) ground wire to the ground plane or
buss bar using a 00 bolted ring or spade lug connector (not supplied).
Connect the other end of the heavy gage ground wire to the ground
rod using the brass rod clamp supplied, or connect to the alternate
interior earth ground point.
e. Verify connection to the earth ground from the case of the Polyphaser.
2. Component Installation:
a. Mount the antenna in the proper orientation, with the connector at the
bottom.
b. Connect one end of the antenna cable to the antenna and install the
cable up to the location of the Polyphaser. Assure that a drip loop is
maintained in the cable at the base of the antenna, and at the point
where the cable will enter a weatherproof enclosure or building. The
drip loops will minimize the amount of rainwater that will run down
the cable to the enclosure or building. NOTE: The minimum bend
radius of the antenna cable is 6 inches. Tight bends in the antenna
cable, or clamps that crush the cable, will damage the internal
insulation and compromise the cable. Handle the antenna cable with
care.
c. Connect the antenna cable to the Polyphaser module connector
marked ANTENNA.
d. Connect one end of the short COAX RPSMA Polyphaser-to-RF401
cable to the EQUIPMENT side of the Polyphaser module, and the
other end to the antenna connector on the RF401.
