3.2 Antenna Options

One of 2 antenna types is included with your system, also specified when ordering:

The external, magnetic mount antenna (part #68-2000-032) is 3 inches tall and has a 6 foot cable. This antenna is for general use, and is especially desirable when the system is stored within an enclosure.

The external, in-streetantenna (part #68-2000-031) is 4” in diameter and 1.75” tall, with a 10 foot long cable. It is used primarily in manhole applications.

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 the installation, fill the holes in with cement.

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.
