This is too easy.
WBZ has been running on reduced power for most of the last few weeks
thanks to an antenna problem:

No clue if it has been fixed, but judging by the lack of updates,
probably not.


Well that takes all the fun out of it!


Occam's Razor.

But do note my post of good reception at 51.9m miles with
cut to length folded dipole, 10 ft off the ground.
Channel 36, about 9.5" long.

Sure, it can be done at 45 miles depending on tx power and frequency.
However, Captain Video has an additional problem in the form of a
mound of dirt in between his antenna and the station transmitter.

or if you have Google Earth handy:

The above path profile is NOT very accurate. I stopped working on the
problem after Captain Video disappeared from the thread.

Incidentally, I sometimes can watch KMPH TV from Fresno, CA which is
about 200 miles away from Ben Lomond. I live on the side of a hill
which helps. The real culprit is atmosheric ducting and edge
diffraction from two mountain ranges in between. It only happens a
few days per year, usually in the summer, but the picture is 100%
perfect.


When I was a lot younger living in Kalamazoo Michigan, late one night
I received a Wisconsin TV station across lake Michigan.
