Ground radials should be attached
to the U-bolts on the Base Mounting Bracket.

The antenna should be
fed using a good quality 50-Ohm low-loss coax such as RG-8 or
RG-58. Approximately 4 inches of the outer insulation should be removed. The center
conductor of the coax should be soldered to the solder lug that was placed on the _” bolt in
step 10 of the assembly. The outer shield of the coax should be soldered to the additional
solder lug supplied in the parts bag. Place this solder lug onto one of the U-bolts located
on the mounting bracket Secure it using one of the _ “nuts supplied with the U-bolts.
WARNING:
Serious burns can be received with improper use of a soldering iron.

USING THE MFJ
GROUND-COUPLED™
PORTABLE ANTENNA BASE WITH THE
MFJ-1795
The antenna base should be assembled using the instructions supplied with the unit. The
following instructions will explain the installation of the MFJ-1795 to the antenna base.
[ ] 1.
The U-bolts should be attached to the base through the holes as indicated in Figure 5.
[ ] 2.
The So-239 connecter, supplied with the base, should then be installed on the top of the
base plate mount as indicated in Figure 6 using two 6/32” x 3/8” screws and kep nuts
supplied with the base. One of the feed-points at the bottom of the base may also be used.
The insulated wire supplied with the MFJ-1904 will be long enough for this application.
This will increase the radiating length of the antenna.
