Optional: Attach the Coil Housing
•
If you are using the optional 40m or 80m coil you
will need to attach the housing at this point.
•
Mount the coil housing to the EHU using four 10
-
32 x
1
-
1/4”
screws through the holes indicated in
the drawing on the right. Place the
0.5”
plastic
spacers between the EHU and coil housing.
•
Notice that the nuts are on the coil housing side.
•
Connect the coax connector from the coil housing
to the EHU.
Install the Mounting Post
•
For ground mounting you will want to ensure that the mounting pole (included) does not
shift or settle over time, using concrete to secure it in the ground is a way to eliminate the
potential for this problem. Position the mounting pole (machined end up) so that the bot-
tom of the element housing is 6 inches above the ground. After the mounting post is in
place and level, you are ready to erect your SteppIR Vertical!
Mount EHU Onto the Mounting Post
•
A rubber quick
-
disconnect boot must be installed (small end first) on the
1
-
1/2”
mast
(ground or elevated mount) before mounting the element housing unit on the mast.
•
After the EHU is mounted on the mast, push the rubber boot up onto the fiberglass ele-
ment support tube firmly until it bottoms out. Tighten the two clamps. This boot will pre-
vent the antenna from turning on the mast. See the photos on the next page for refer-
ence.
