Bigger LoG Antenna Addendum

Two things regarding the new 128-ft Loop on Ground antenna:

1. I forgot to mention that the signals from the new LoG antenna were so strong that my IC-R8600 receiver’s OVF (Overflow) indicator lit up tuning throughout the AM band indicating that an excessively strong signal was being received. To fix that, I turned the RF gain down from 90% to 84%.

2. For the isolation transformer, I used an inexpensive 300 to 75 ohm balun – the kind that often came with old VCRs and TVs that have F-connector inputs. I collected a few over the years and put one to good use.
