MFJ-1795 Vertical Antenna
Instructions
4
[ ] Quality low-loss 50-Ohm coax with a PL-259 to go from the antenna to the transmitter.
[ ] Either a SWR meter or Analyzer (MFJ-259, 269)
SAFETY PRECAUTIONS:
WARNING:
You can be killed if the antenna, feedline, or the equipment used to install
the antenna accidentally contacts any utility lines. Never install an antenna near power
lines!
1.
Be careful while carrying the antenna. It is heavy enough to cause you to lose your balance if
it is handled too casually or if the capacitance spokes become entangled in obstructions.
2.
Mount the antenna in a way so that it is out of reach. The ends of the capacitance spokes can
cause eye injury, serious RF burns or both.
3.
Make sure that a mast, if used, is sturdy enough to support the weight and the wind load.
ASSEMBLY AND INSTALLATION PROCEDURE
During assembly of this antenna refer to the figures in this manual and the picture on Page 1.
NOTE:
Wear safety glasses whenever working on or near this antenna.
Do not tighten the screws that connect the loading coil terminal lugs to the capacitance
hats or
you will BREAK the fiberglass form. If the terminal lugs loosen tighten the NUT on the lug.
STEP-BY-STEP PROCEDURE
[ ] 1.
Prepare a temporary work surface, such as a table, two saw horses, or trash cans, to be
used while installing the parts onto the antenna.
[ ] 2.
Sort out the parts you have unpacked into groups of similar parts. Be sure all the parts are
available.
[ ] 3.
After examining the antenna parts, gather the tools needed for basic assembly. At the
minimum these consist of:
[ ]
#1 Long Phillips screwdriver for capacitance spoke screws
[ ]
1/4" flathead screwdriver or a 5/16" nut driver for hose clamps.
