• The external, magnetic mount antenna (part
#68-2000-047) is 6 feet long and 5 inches tall. This
external antenna is for general use, and is especially
desirable when the system is stored within an enclosure.

• The external, in-street antenna (part #68-2000-031) is
10 feet long, and used primarily in manhole applica-
tions.
The antenna is buried next to the manhole, in a hole
bored into the pavement, at a depth leaving the top of
the antenna flush with the street.
A connecting hole is drilled through the manhole collar
for the antenna’s cable. To complete installation, fill the
holes in with cement.

4.3.1 Connecting the
Antenna
The antennas are connected to the 2103

using the connector on
the right hand side of the module.
The two types of antennas use a protective connector shell on the
end of the cable to protect the end connector from the elements.
On the magnetic mount antenna, this connector shell is installed
at the factory. If you order an in-street antenna, the shell is left
off to make it easier to install the buried antenna.
