Hardware Installation
The EFM-100 field mill mounts on a ¾” NPT (National Pipe Thread) threaded pipe (Note
that ¾” NPT pipe measures 1” outside diameter)
A short length of ¾” NPT threaded pipe and a ¾” NPT mounting flange are provided for
mounting the field mill on a horizontal surface. Longer lengths of threaded pipe are
available at your local hardware store. Antenna mounting tripods are available at your local
Radio Shack store or your local television antenna installer (see Television Antennas in
your Yellow Pages).
Install the EFM-100 Field Mill on a calm clear day when no thunderstorms
are expected.
Your local antenna installer can do a safe and professional field mill installation and can
also ensure that the field mill is properly grounded.
If you are not experienced in safe antenna installation using appropriate safety
equipment you should refer installation to an experienced antenna installer.
(See Television Antennas in the Yellow Pages)
Choosing an Outdoor Mounting Location
If possible choose a mounting location for your field mill which will provide easy access
for maintenance. While your field mill should run for many years with little or no
maintenance, cleaning or de-icing may occasionally become necessary. A location which is
easy to access can make this a much easier and safer task.
The choice of a mounting location can affect the operation of the field mill. In general,
higher is better.
ELECTROCUTION HAZARD
You can be killed if the field mill or its mounting hardware comes in
contact with an electrical power line. WATCH FOR AND STAY AWAY
FROM ALL OVERHEAD WIRES.
