I don't have an AH-4 but if the AH-4 is like the SGC-230 (in terms of 
specified operating frequencies) then both ranges are probably correct. 
I have two SGC-230's, one for mobile (using the QMS-2 system) and a 
second for home use with my low powered (under 200 watt output) gear. 
The SGC-230 is spec'ed for 1.8 to 30 when used with a 23 min length 
antenna, but only 3.5 to 30mc when used with the min 8' mobile whip. 
That may be the same with the AH-4 and why you see two different 
operating ranges, depends on the min antenna length used.

However, I have no problem using my SGC-230 to load my SG-303 whip (9' 
helical wound) on 160 meters and have used it 160 mobile many times, it 
certainly isn't very efficient and doesn't get out like gangbusters, but 
it does work and it's fun to have guys come back and say "your MOBILE on 
160?"

For those with newer rigs that cover 6 meters, SGC makes other tuners 
that cover up to 60mc, as the SGC-230 stops at 30mc.
