you've got it...
The next thing to consider is the signal strength in the air... Suppose you have a signal with a noise margin of +40 dB and an HD1200... Add the antenna gain and you would normally expect the net NM to increase (presuming the antenna provided some gain) however, from the rear it would work out like this, +40 dB + (-11.4 dBd) = 28.6 dB net NM ---- Which would still be plenty of signal power, presuming there are not sources of interference to contend with.
From what I see on your report, I expect you will have no problem receiving real CH-8 & CH-47 with an HD1200 or HD1800 pointed in the opposite direction. (Presuming there are no significant issues with interference.)
