MFJ-1763 Portable Beam Antenna
Instruction Manual
3
Assembly Instructions
1- Separate the elements according to length.
2- Screw a 1/4-20 Nut onto each of the elements. Once the antenna is
assembled and tuned these nuts will lock the elements in place.
Refer To Figure 1 For The Following Assembly Procedures
3- Screw the Reflector Elements (Items A) into their designated holes
labeled "Hole A" on Figure 1.
3- Screw the Driven Elements (Items B) into their designated holes
labeled "Hole B" on Figures 1 and 2.
5-3- Screw the Director Elements (Items C) into their designated holes labeled "Hole C" on Figure 1.
NOTE
All elements should be screwed completely into the chassis and then backed out a 1/4 turn.
6- Lock the elements in place by tightening the 1/4-20 Nut against the chassis.
7- Mount the U-bolt assembly in the appropriate mounting holes as shown in Figure 1. Keep in mind the
polarization of the antenna (See Fig. 1).
8- The assembly is now completed and the antenna can be mounted on a mast to be tested for SWR
before transmitting.
INSTALLATION INSTRUCTIONS
The MFJ-1763 can be mounted on any 1" to 1 ½" diameter mast. The mast may be a conductive (metal)
or a non-conductive (fiberglass) material.
WARNING:
DO NOT MOUNT ANTENNA NEAR POWER LINES.
Death or serious injury can result!
For optimum performance the antenna should be mounted as high as possible. However, if the mast
itself is located on a high elevation, such as a hill or mountain, the need for a tall mast will not be as
critical.
The MFJ-1763 may be mounted horizontally or vertically. The antenna should be mounted horizontally
for SSB and vertically for FM operation.
