devices should have a solid connection to earth via a ground stake or ground grid if the soil has poor
conductivity. Solid connection means a large capacity conductor (not a small wire) with no coils or sharp
bends. All other devices connected to the 95/TX, such as remote strobes or horns, should be grounded to
the same ground point if possible. There can be significant resistance between different ground points
leading to very large voltage differences during lightning activity.
It is very difficult to protect against direct lightning strikes but the probability of a direct strike at any one
location is very small. Unfortunately, power line surges and electromagnetic energy in the air can induce
high voltage surges from lightning activity several miles away.
SEALING ANTENNA AND CABLE FITTINGS
If a coax cable connects to the antenna via connectors, it is very important to weatherproof the
connection using #1000-2314 or equivalent sealing tape. Moisture ingress into a coax cable connection is
the most common cause of problems with antenna installations. A three layer sealing process is
recommended – an initial layer of electrical PVC tape, followed by a second layer of self-vulcanizing
weatherproofing tape (#1000-2314), with a final layer of electrical PVC tape.
USE IN HAZARDOUS AREAS
The 95/TX enclosure is certified for use in Class 1 Division 1 hazardous areas. The standard 10-0295
antenna coupler is designed to meet Class I Division 2 hazardous area standards but is not 3

party
certified.
