pp A3, section III implies that noise in the low VHF band requires at least 13 dB better net NM (per TV Fool prediction corrected for antenna gain and system losses including amplifier NF) than UHF band.

@ TG, This seems quite consistent with your observations and summary.

I generally try to achieve a minimum net NM of +10 dB in the UHF band. So I feel no guilt targeting a minimum of +23 net NM in the low VHF band. When dealing with edge-path signals, I expect these minimums to be inadequate.
