When the HG3 QRO 80m-30m option kit is installed on a HG3 QRO Magnetic Loop Antenna (MLA), full power on
80m, 60m, 40m and 30m operation is implemented. The HG3 QRO allows selection and tuning on these bands.
Operation from 20m to 10m is not possible with the option installed.
What you get:
•
The LMR600 radiation loop
•
Two each “L” SO239 connectors
•
Six-inch SO239 extensions
•
Two radiation loop spacers
•
Two zip ties
•
One Adel type clamp
•
Arduino microprocessor with latest
firmware
Assembly:
The
80m-30m option
adds an additional turn to the existing HG3 radiator loop by connecting it in series
with it. The added inductive reactance allows tuning the entire 80m-30m bands (3MHz-10MHz). Follow
these steps:
1.
Secure loop to the back of the mast using the existing bracket. Do not tighten the bracket at
this time. It will be tightened after all components are installed.
