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 GASMAX/TX enclosure and sensor head with integral flame arrestor are certified for use in Class 1
Division 1 hazardous areas. When combined with the optional XX Class I Division 1 antenna coupler, the
entire device is suitable for use in Class 1 Division 1 areas. The standard 10-0295 antenna coupler is
designed to meet Class I Division 2 hazardous area standards but is not 3
rd
party certified. GASMAX/TX
detectors with sensor heads for reactive gases (without flame arrestors) should not be installed in
hazardous areas.
