MFJ-1622 Window Mount Antenna

Introduction

The MFJ-1622 Antenna was designed to provide portable or permanent HF communications on
40 through 10 meters and VHF on 6 and 2 meters. The universal mount design allows the user to
install the antenna in many ways. The mount will easily attach to window frames, balconies, and
railings. The MFJ-1622 works well indoors mounted to a desk or table as well.
The antenna consists of a collapsible whip, loading coil assembly, universal mount, counterpoise
wire, and choke. The operating frequency is adjusted by moving the tap on the coil. The
counterpoise wire length is adjusted for minimum SWR. The MFJ-1622 Antenna will allow the
operator to get on the air from locations where antenna size is limited.

Choosing a Mounting Position

WARNING: ALWAYS ATTACH THE SAFETY ROPE TO A STABLE SUPPORT
BEFORE ATTEMPTING TO ATTACH THE UNIVERSAL MOUNT TO A
WINDOW FRAME OR RAIL. INJURY AND DAMAGE COULD OCCUR
IF THE ANTENNA WERE TO FALL.
The design of the antenna allows it to be installed in many ways. It can be easily attached to a
window frame, window box or balcony railing. A Wooden fence is another common mounting
location.
The best performance will be obtained by placing the antenna outside, however the antenna may
be used indoors if necessary. The base plate may be attached to a table, book shelf, or other
suitable support. The counterpoise is simply placed on the floor. Some installations may require
the use of a C-clamp or vice-grips to secure the base plate. Always remember to keep the
antenna away from metal objects and out of reach to prevent injury.
WARNING: SERIOUS RF BURNS AND INJURY CAN OCCUR IF CONTACT IS
MADE WITH THE ANTENNA.
