5.6.6.4 External Installation of the Wi-Fi Modem
The 2.4 GHz/5.8 dBd Omnidirectional Wi-Fi Antenna should have been
ordered with the kit.
To mount the antenna onto the ET107 pole, the Wi-Fi accessory kit contains
the following hardware:
(1) antenna cable, 59 inch
(1) adjustable angle antenna mounting bracket
(1) 5/16-18 x 2.125 stainless steel U-bolt
(1) CM230 saddle bracket
(4) silicon bronze 5/16-18 nuts
(4) 5/16 stainless steel washers
(4) 5/16 stainless steel lock washers
(4) 14.5-inch black UV resistant wire ties
1.
Fasten the mounting hardware onto the ET107 pole by following steps 1

(p. 38)
.
2.
Slide the back of the antenna into the saddle bracket and tighten its nuts to
hold the antenna firmly in place.
Do NOT over tighten the nuts on the saddle bracket or you
might damage the antenna.
3.
Adjust the antenna cable at the BNC connector so the cable cover fits over
all the sensor cables as well as the antenna cable. You may have to gently
bend the antenna cable to put a 90° bend by the BNC connector end of the
cable. Take the cover off when you’re done.
4.
Use one of the black wire ties to strap the antenna cable to the bundle of
sensor cables.
5.
Tighten the wire ties holding the antenna cable to the wire tie mount at the
top of the enclosure.
6.
Take one black wire tie and strap the antenna cable to the antenna. Leave
some slack on the cable between the wire tie and the antenna connector so
as not to stress the connector/cable connection.
7.
Wire tie the antenna cable to the pole. Clean up the wire ties and put the
cable cover back on.
