Thanks for sharing your diy experience, it looks like a fun exercise.

I used one of these


for 3 years in north Fargo. We were located roughly on a straight line
between Fox's tower SSE of town and the PBS/NBC/CBS/ABC cluster NNW of
town (secondary stns were broadcast on each, too). IIRC, Fox's tower was
15 miles away and the NNW cluster was 35-40 miles away. Sitting in my
2nd floor office with metal siding, a pretty mature urban forest and
water tower in the line of sight, that antenna brought in the stations
NNW of us with about 90% reliability; Fox's broadcasts were more like
10%. Spring and fall were bad reception times, but winter and summer
were fine. I would guess the broadcasters ineptly adjusted their power
to the changing foliage in spring/fall, but that's just a guess.

I had intended on replacing the cheapo with an exterior antenna, but
since we didn't watch Fox much, I never got around to it.

When we moved to Winnipeg, I discovered a second nice feature of this
cheapo antenna: it does very well (better?) when pointed at right angles
to a tower. That's good news, because the two towers (CTV v. Global/CBC)
are about 100 degrees apart from my location. I think the CTV tower
actually has too much power for the hardware, which leads to lots of bad
recordings when the antenna is pointed at the tower.
