2.4 LNA Installation
Refer to Section 2.2.1 for included parts.
To install a single LNA to an antenna:
1. Remove the protective cover from the antenna mount location (if installed).
2. Remove the plastic cover from the antenna end (RF IN) of the LNA.
3. Remove the plastic cover from the RF OUT end of the LNA.
CAUTION
After removing the protective cover(s), ensure that no foreign
material or moisture enters the antenna waveguide or LNA.
4. Install the appropriate gasket on the antenna end of the LNA:
a. If the LNA has a groove, and the antenna flange does not, the thin gasket
should be used.
b. If both the LNA and antenna flanges have grooves, the thick gasket should
be used.
5. Position the LNA in place on the antenna, and install the 1/4-20 bolts, washers,
and nuts. Do not tighten at this time.
