FIGURE 6-32. Mount antenna saddle bracket
NOTE:
Only rotate enclosure if needed to allow aiming of the Yagi antenna to the base
antenna. Keep solar radiation sensor towards the south as much as possible. Rotate
wind sensor to realign as needed.
9. Use the following procedure to install the Yagi antenna for the radio. Installation of the
omnidirectional antenna is similar (
(p. 49)).
NOTE:
Mounting hardware that comes in the box with the Yagi antenna will not be used.
a. Slide the back of the Yagi antenna into the saddle bracket.
b. If the Yagi antenna at the station is communicating with an omnidirectional antenna
at the base, align the tines on the Yagi antenna so they are vertical (
48)). If two Yagi antennas are used at both ends of communication, align the tines
the same. If interference is a concern, align the tines on the two Yagi antennas
horizontally instead of vertically. This will put the signal out of phase with other
antennas that are aligned vertically.
c. Tighten the nuts on saddle bracket to hold the antenna firmly in place.
CAUTION:
Do NOT over tighten the nuts on the saddle bracket or damage to the antenna
may occur.
