ANTENNA HEIGHT
The height of the radiating element is adjustable from 5 to 8 feet. Maximum radiation will be
obtained by setting the height of the radiating element at 8 feet. Some installations may require
the antenna height to be reduced. An example may be the installation of the antenna inside a
backyard fence for concealment. Height adjustment will be discussed in the assembly section of
this manual.
INSTALLATION
The MFJ-1795 was designed as a low profile, portable antenna. When combined with the MFJ
Ground-Coupled
™ Portable Antenna Base the antenna will provide permanent or portable
communications. This is an ideal antenna for restricted locations. However, the antenna
installation MUST be protected with non-metallic fencing to provide personal safety and to
prevent antenna damage. The antenna can be installed using the supplied mounting bracket and
a suitable ground radial system.
IMPORTANT
:
A suitable ground plane must be installed with this antenna.
PORTABLE SETUP
The antenna may be disassembled to the extent necessary for transporting to a temporary
location. Before the antenna is disassembled, some type of marks should be placed on the mast
of the antenna to ensure it will be the same height as before.
Some retuning may be required
after moving the antenna.
