frequency.
Connect the Base Matching Network Assembly and adjust the inductance by changing
the tap connection and watch for a change in SWR to obtain the best impedance match.
Once final tuning is complete and you have verified correct operation on-the-air, the
DXE-VMN-1
coil tap should be soldered in place to eliminate any future intermittent connection due to
environmental corrosion to the coil taps.
Guying a Vertical Antenna System
Guying of vertical antennas is always recommended for stability. However, if your area encounters
severe wind velocities or icing conditions, simple guying will reduce the possibility of failure.
Using the
DXE-GUY
kits, you can install four guy ropes starting approximately 1/2 the way up the
vertical antenna system to ground level. Guying should be tightened just enough to permit the
antenna to swing a few inches. The ends of the ropes are tied to the earth anchors that are screwed
into the ground at about the same angle as the ropes will be. When using the Tilt Base, position the
guy wires as shown below. This will make it easy to raise or lower the antenna and only one guy
line needs to be loosened. The other guy lines will help guide the antenna on the way up. Depending
on your antenna system, additional guys at higher points on the antenna may be required.
