2.0 INSTALLATION
2.1 Site Selection
2.1.1 Antenna
The receiver antenna should be installed at an elevation that is as high as practical. If
possible, install the antenna onto a radio tower, tall building, or other tall structure. Refer
to Radio Path Survey.
2.1.2 5052RD-K
The 5052RD-K ALERT2 Receiver/Decoder enclosure should be located near the antenna
tower to reduce the length of the RF transmission line and the associated RF signal loss.
It is recommended that a lightning arrestor with ground lug (optional) be placed between
the ALERT2 receiver back panel BNC connector and the antenna to protect against
lightning damage.
