Antenna Directionality

Just wondering if TV Fool's modeling algorithms include antenna directionality in the output results - from what I've read they don't appear to, so I am curious as to whether or not this is indeed the case as certain stations that I've tried to receive haven't come in at all despite lower-NM stations coming in just fine with the same antenna.

For example, if a particular station or translator broadcasts using a highly-directional antenna, and the location of interest is not in the direction the antenna is pointing, then I presume this would greatly decrease the NM at the location being queried? I know FCCdata/RECnet has the antenna directionality type given where known and I was wondering if TV Fool includes this in its modeling.

Thanks for the help and I greatly appreciate how useful and versatile TV Fool and FM Fool are.
