Looks like the CM 4228 old style was a little over 5db gain around the channel 10 area, whereas the YA1713 is about 10db gain. That with the slightly less powerful AP3700 preamp (17db) pulls in my VHF-12 pretty well. I was a solid 80 yesterday afternoon and mid-80's to around 90% in the morning and evening. Drop outs have been a little annoying but so far not unwatchable. It is about as much as I can ask from VHF digital. Lots of storms in the area today so I'll see how it goes with that happening.
