That equates to antenna gain of 19 dB in theory (assuming a preamp NF of 3 dB).
In the real world, a 10 dB 'fade' margin is cutting it quite close. Engineering for a margin of 15 dB is not overkill by any means (IMO). So I'm suggesting an antenna with 29 to 34 dB of forward gain. (I know of no such antenna on the consumer or commercial market.)
Reception of a signal arriving at a NM of -16 dB is going to be impossible in some cases, unreliable in others. In a few cases, you'll get lucky and find that the prediction was off in some way.
It may be more practical to find a friend in Bellingham or Lynden who would allow you to operate a HTPC or Slingbox remotely.

What's funny is that I can get CHEK 6 VHF analog and they show NM of -10 dB. Heheh...
As for that slingbox idea, yeah, I thought about that.. wonder why there's not a website that would do something like this? I guess it would be a copyright issue, huh?
