[ ] Locate two radial rings and place
together so cupped grooves oppose.
[ ] Install two 5/8” screws from top side, as shown.
[ ] From bottom side, install a #10 spacer washer and support bracket on each screw.
[ ] Secure assembly using lock
washers and nuts (finger-tighten
only for now).
[ ] Install six 5/8”
screws in remaining holes, secure with lock
washers and nuts.
[ ] Set assembly aside for later installation.

[ ] Locate two radial clips and place together so cupped grooves oppose.
[ ] Insert two 5/8” screws from top side, as shown.
[ ] Install a spacer washer from bottom side on each screw.
[ ] Insert both screws down through the radial-clip bracket, as shown.
[ ] Secure bracket in place with lock
washers and nuts (finger-tighten only).
[ ] Set assembly aside for later installation.

Important Note:
More than the prescribed number of radials may be installed on the MA8040V at your
option
in order to optimize radiation efficiency. However, note that as radials are added, SWR may
eventually increase to an unacceptable level as driving resistance drops progressively further below 50
Ohms.
Use the best compromise for your operating location.
Step-13: Install Resonator on Vertical Radiator

[ ] Slip the resonator tube inside the top of 1-1/8” radiator tube BE (
Figure-13
).
[ ] Position the contact lugs over the tubing mounting holes, as shown.
[ ] Using a 1-1/2” screw and 8-32 nut, secure resonator tube and coil wires in place. Tighten securely.
