ET107 Weather Station
To mount the antenna onto the ET pole, the 19256 Cell Phone Accessory Kit
contains the following hardware, which is the same hardware used in the 20586
RF450 kit:
(1) 14241 Antenna Cable – 59 inch
(1) 18290 ET Antenna Adjustable Angle Mounting Bracket
(1) 17492 5/16-18 x 2.125 Stainless Steel U-bolt
(1) 17851 CM230 Saddle Bracket
(4) Silicon Bronze 5/16-18 Nuts
(4) 4365 5/16 Stainless Steel Washers
(4) 4366 5/16 Stainless Steel Lock Washers
(6) 17592 14.5 inch Black UV Resistant Wire Ties
1. Fasten the mounting hardware onto the ET107 pole by following steps 1
through 4 in Section 2.5.4.4, External Installation.
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 10530 Yagi antenna, orient the antenna so it’s aimed at the
cellular tower. 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 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.
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.
