Well look at this. In his first post he made what could be considered an accurate comparison between two antennas that enabled him to determine which one was better. No need to argue meter accuracy, switch box isolation or interaction from the previous installed antenna. Even with your eyes closed he can hear the difference in the distant stations. This is all consistent with the advertised gain.
Refreshing, isn't it!
I do wonder if that's on AM, FM or SSB, and if any other changes were applied, height, grounding, coax/connectors, age & tuning of of Imax, etc.
2 S-units is a considerable increase, and a full 1 S-unit more than I saw when switching from my I2K to the SGM.
I'd venture an inspired guess that he's definitely one happy camper.
