Antenna Installation Options
Direct-Mount Antenna
Each Scanner 3300 wireless device is equipped with a wireless module. Antennas and antenna cable are optionally avail-
able. The installation of the antennas and antenna cable must meet the requirements shown in Figure 2.6, page 26 and
Figure 2.7, page 26 .
Remote-Mount Antenna for Pole Outside Diameters up to 2 Inches
The standard hardware supplied with Sensia’s remote-mount antenna can be used to mount the antenna to a pole with an
outside diameter of 2 in. or less. The supplied hardware includes two U-bolts, two toothed brackets, four lock washers
and four nuts.
Note If a 2-in. pipe with a 2 3/8-in. outside diameter is to be used, consider using Sensia’s 2-in. pipe mount hardware
kit.
To install the antenna, reference Figure 2.9 while following the instructions below:
1. Position the antenna with the shiny metal base against a vertical pole and the capped end of the antenna vertical in
the air. Note the N-female cable connector at the bottom of the metal base for connecting antenna cable.
2. Position a U-bolt around the antenna and pole, placing the bend of the U-bolt against the antenna base.
3. Place a toothed bracket over the threaded legs of the U-bolt with the teeth facing the pole and slide the bracket snug-
ly against the pole.
4. Install a lock washer and a nut on each of the two U-bolt legs extending through the toothed bracket.
5. Repeat steps 2 through 4 to install the second U-bolt and toothed bracket to secure the base of the antenna.
6. Attach the antenna cable to the N-female cable connector at the bottom of the antenna.
