3.
Hold the Extender and mounting brackets in place and tighten band clamps.
•
The Extender may be mounted with either an Up or Down antenna orientation to obtain the
best communication path for your location.
4.
Mount the optional power disconnect box on the pole with stainless steel band and brackets or
non-corrosive bolts to tapped holes, according to local codes and best practices.
5.
Attach the wires from the Extender to the screws on the terminal blocks inside the power
disconnect box.
•
For any cables in an assembly, allow some slack to rest below metal parts. The slack is
called a “drip loop”. With a drip loop, water from rain and condensation drips from the cable
without damaging associated mechanical equipment.
6.
With the power disconnect switch in the OFF (open) position, make the connection between the
Extender, power disconnect switch, and power source according to local codes and best
practices.
•
Installations where the power cable is wired directly to the power source must be sealed with
waterproofing compound to prevent water ingress into the power cable.
7.
Using UV stable tie wraps, secure the power cable to the pole.
•
Gyr recommends tie wraps that are 1/2” to 3/4” wide.
•
While securing the power cable to the pole, care must be taken to NOT DAMAGE the outer
jacket of the power cable. A nick in the outer jacket will allow water to migrate inside the
power disconnect switch and flood it.
•
Provide enough tension relief and a drip loop for the power cable.
8.
Securely hand tighten the included antenna on the antenna mounting connector on the Extender.
•
The antenna should never be more than 10° off in any direction from being perpendicular to
the ground.
•
If the Extender is mounted upside down (antenna up), always inspect and verify the presence
of an O-ring on the antenna base. The O-ring is included with the antenna. Verify that the O-
ring has no physical deformities that could compromise the water tight seal at the base of the
antenna.
