antenna and saddle bracket to point correctly in the vertical

direction.

iii. 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.

iv. Use one of the black wire ties to strap the antenna cable to the

bundle of sensor cables.

v. Tighten up the wire ties holding the antenna cable to the wire tie

mount at the top of the enclosure.

vi. Take one black wire tie and strap the antenna cable to the antenna

as shown in FIGURE 2-38. Leave a little slack on the cable

between the wire tie and the antenna connector so as not to stress

the connector/cable connection.

vii. Make sure there is a loop of antenna cable directly under the Yagi

antenna. This will act as a drip loop and allow moisture to run off

the antenna and cable. See FIGURE 2-38.

viii. Wire tie the antenna cable to the pole. Clean up the wire ties and

put the cable cover back on.
