a little late, but....
Here is a sweep of the HPN-30118. My service monitor doesn't have markers, so I had to add some graphics.
Would I be correct that in your full notch (pic #1), those are 100 Mhz segments on the scope? And on the second pic (showing VHF-low and the FM notch) those are 10 Mhz segments?
I am thinking about getting one of these, but I feed multiple scanners and I'd really hate to be 10 db+ down from 34 Mhz and lower. I was hoping the high pass filter effects would be minimal at 30 Mhz.
