Chapter 4 Antenna Installation
The FWB-205 Kit and its two 19 dBi antennas are intended for fixed, point-to-point applications only. Any
other use is prohibited. Antenna(s) for the FWB-205 outdoor unit must be installed by a qualified profes-
sional. Operation of the unit with non-approved antennas is a violation of U.S. FCC Rules, Part 15.203(c),
Code of Federal Regulations, Title 47.
The FWB-205 units have three antenna connectors for each radio. Each FWB-205 unit should be installed
with its antenna on a sturdy pole or mast. It does not matter whether you install the antenna first or the
radio unit first. In all cases, antennas should be installed by a qualified professional. Outdoor installations
MUST have code-approved grounding and lightning-protection systems.
An assembled and mounted antenna is shown in Figure 4. The mounting systems consists of a pole clamp
assembly, a pivot link, and an antenna bracket. These are shown in Figure 5.

Begin assembly by attaching the pivot link to the pole clamp assembly, as shown at left in Figure 5. Use
a flat washer under the bolt head, and under the nut use a flat washer and lock washer.
Next, attach the pole clamp assembly to the pole, as shown at center in Figure 5. Again, use a flat washer
under the bolt heads, and under the nuts use a flat washer and lock washer.
Mount the antenna bracket to the antenna such that the mounting lug is horizontal when the top of the
antenna is up, as shown at right in Figure 5. Antenna polarizations must match between the two ends
of a link.
