Section 2. Hardware Installation
Rotate enclosure to expose antenna. Ensure that the solar
radiation sensor is not shaded.
NOTE
5. Use the following procedure to install the Yagi antenna.
Mounting hardware that comes in the box with the Yagi antenna
will not be used.
NOTE
i. Slide the back of the Yagi antenna into the saddle bracket. If the
Yagi antenna at the station is communicating with an
omnidirectional antenna at the base then align the tines on the
Yagi antenna so they are vertical. See Figure 2.5-12.
If two Yagi antennas are used at both ends of communication
then align the tines the same. If interference is a concern then
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.
Tighten the nuts on saddle bracket to hold the antenna firmly in
place. Do NOT over tighten the nuts on the saddle bracket or
damage to the antenna may occur.

ii. Orient the Yagi antenna so it’s aimed at the base antenna. You
may have to flip the adjustable angle bracket over to get the
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
