Meridian Companion Installation and Maintenance Guide
Installing an outdoor omnidirectional external antenna
• Locate the antenna on the external wall of the building.
Note: The antenna must be mounted on a vertical surface.
• Keep the outdoor omnidirectional external antenna as close as possible
to the Base Station serving it (the Base Station must be inside). The
recommended mounting height is 4 to 5 m above ground level.
• Always install a lightning surge arrestor between an outdoor
omnidirectional antenna and a Base Station.
Note: The connector on the outdoor omnidirectional antenna is a TNC
female connector, so you need an adapter to connect it to the
standard BNC coaxial cables needed for the lightning surge
arrestor and the Base Station. You can also use a coaxial cable
with a TNC male connector on one end and BNC male
connector on the other end.
ATTENTION!
Fit the lightning protection to the antenna if appropriate.
See “Installing a lightning surge arrestor.”
ATTENTION!
Do not install the external antenna or the lightning surge
arrestor during an electrical storm.
Always turn off the Base Station power before connecting the
coaxial cable of an outdoor external antenna.
Always install the lightning surge arrestor as close as
possible to the cable entry point into the building.
Connect the lightning surge arrestor to ground before
connecting the coaxial cable
