This latest re-design of the AL series base insulator totally liberates the
Full performance of these verticals. They yield a very low base capacitance (pF).
WARNING: Avoid HAZARDOUS LOCATIONS. Stay Clear of Power Lines
And or any overhead obstructions.

CHOOSING A LOCATION FOR THE ANTENNA
For best performance, mount the antenna in a clear location away from
buildings, towers, feedlines, utility wires, and other antennas.
Never mount this antenna in a location that will permit unsuspecting
people to come in contact with any part of the antenna.
Never mount this antenna where a mechanical failure might allow the
antenna to contact power lines or other utility wires.
Always ground the feedline to a good earth ground at the point where It
enters a building for lightning protection.
NOTE:
First, check the parts you received. The
BOM to the left is the quantity per element upgrade.
.
Please take the time to read and understand the
Assembly procedures to ensure a great installation.

Element UPGRADE Assembly Instructions
1. Please review the last page. These are the mounting dimensions when attaching the vertical and insulator to the mount.
REFERENCE ONLY--
2. Lower all verticals. Remove the existing base insulator as it will be retired.
3. Insert the base .875” X 12” tube over the base of the Fiberglas insulator until the holes line up. Insert 6X32X1.5” SS PH screw
and attach with 6X32 SS K-lock nut and tighten.
4. Take the large element base end (.875” x 72”) and insert it over the insulator as mentioned in step 3 until it is 1” way from
the .875” X 12” tube. Drill a number 6 clearance hole through the .875” x 72” element base tube and insulator so the hole is
about ½” on the base element tube. Inserted a 6x32x1.5”SS PH screw through the drilled hole and attach with 6x32 SS K-
lock not and tighten. Add one more K-Lock on this screw and leave finger tight for now. THIS WILL BE THE ELEMENT
CONNECTION TERMINAL. See pg 5 and 6.
5. Repeat steps 3 and 4 to complete the upgrade for ALL elements.
6. Note image on last page for re-mounting the vertical to your mounts. We want the 12”x.875” tube to attach to the mount so
the upper edge is flush with the top of the angle mount. Use the new#20 SS clamps. Use the PVC as shown to contain the
.875” X 12” as shown in the image. Tighten the 12” tube with PVC shim with the SS clamps. You do not have to crush it, just
tight.
7. Reconnect the Hi-Z Amp. Use the 5 inch wire to connect to ground terminal on mount. Use the 13” wire to connect the
Element / Antenna terminal from the Hi-Z Amp to the element terminal as discussed in step 4 above.
8. Re-attach the Hi-Z Amps as shown in the image. Note the pg 4. Drill two holes as shown in the existing 4 inch tubing and
push a cable ties through and pull it together, does not have to be tight as it is ONLY holding the hi-Z Amp inside the tube.
