3.3 Antenna Installation
For the COM, VOR/LOC, and Glideslope antenna, follow the manufacturers’ instructions. Avoid running
other wires and coaxial cables near the VOR/LOC antenna cable.
Do not use construction grade RTV sealant or sealants containing acetic acid. These
sealants may damage the electrical connections to the antenna. Use of these type sealants
may void the antenna warranty.
3.4 Cable Installation
1. Route the coaxial cable to the rack location keeping in mind the recommendations of Section 2.
Secure the cable in accordance with good aviation practice.
2. Trim the coaxial cable to the desired length and install the BNC connector (330-00087-00) per the
cabling instructions on Figure 3-1. If the connector is provided by the installer, follow the
connector manufacturer’s instructions for cable preparation.
