SteppIR Antennas - 80m Loading Coil Kit

Mounting the Coil Housing:
•
Mount the coil housing to the element housing unit using (4) 10-32x1-1/4 in. screws and
(4) 1/2 in. standoffs with the terminals at the bottom (Figure 9 & Figure 11).
Note: For the BigIR MK III it is recommended that you insert the (4) 10-32x1-1/4 in. screws
from the coil side (opposite of Figure 9 & Figure 11) to allow clearance for the nuts.
•
Connect the output lead of the coil to the ground lug on the bottom of the element hous-
ing unit.
•
Use plenty of silicone to protect the high voltage RF connection (ground lug) on the bot-
tom of the element housing unit.
•
Reconnect the coax feed line along with the 1:1 balun (if used).
Removing the Small Screw in the CPVC Element Liner Coupler.
•
At the end of the first section of 3/4” CPVC liner there is a coupling held in place with a
small screw (Figure 13). Remove this screw, it could potentially react to the high volt-
age RF present when using the coil.
•
Carefully remove the coupling, apply PVC glue (supplied) and reinstall the coupling
making sure that it is seated firmly (Figure 15).
