5.6.5.5 External Installation of a Cellular Modem
The antenna should have been ordered with the kit.
Mounting hardware that comes in the box with the antenna will
not be used.
To mount the antenna onto the ET107 pole, the cell phone accessory kit
contains the following hardware, which is the same hardware used in the
spread spectrum radio kit:
(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
(6) 14.5-inch black UV resistant wire ties
1.
Fasten the mounting hardware onto the ET107 pole by following steps 1
External Installation of the Radio
(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.
If using the Yagi antenna, aim the antenna at the cellular pole. You may
have to flip the adjustable angle bracket over to get the antenna and saddle
bracket to point correctly in the vertical direction.
4.
Adjust the antenna cable at the BNC connector so the cable cover fits over
all the sensor cables and 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.
5.
Use one of the black wire ties to strap the antenna cable to the bundle of
sensor cables.
6.
Tighten up the wire ties holding the antenna cable to the wire tie mount at
the top of the enclosure.
7.
Take one black wire tie and strap the antenna cable to the antenna. Leave a
little slack on the cable between the wire tie and the antenna connector so
as not to stress the connector/cable connection.
8.
Wire tie the antenna cable to the pole. Clean up the wire ties and put the
cable cover back on.
