How did you get those tower line of site overlays into that picture? That's very cool!
I used the TVFool Interactive Browser:

The green signal lines are based on old channel data, but it gives the general idea.



Channels checked:

4-1 (KRDK) COZI, Real channel 24, 324.8 deg True, Signal Margin 39 dB
6-1 (WDAY) ABC, Real channel 21, 306.1 deg True, Signal Margin 68 dB
11-1 (KVLY) NBC/CBS, Real channel 36, 331.6 deg True, Signal Margin 53 dB
13-1 (KFME) PBS, Real channel 13, 307.5 deg True, Signal Margin 59 dB
15-1 (KVRR) Fox, Real channel 19, 111.7 deg True, Signal Margin 56 dB
28-1 (K28MA) CBS/CW, Real channel 28, 331.6 deg True, Signal Margin 40 dB
30-1 (KXJB) CBS/CW, Real channel 30, 101.7 deg True, Signal Margin 60 dB

I now have the antenna connected to a Tablo Quad (4-tuner) DVR. The problem I'm having right now is that I occasionally get dropped recordings for
channels
4-1
11-1
15-1
28-1

It doesn't happen all the time. I'm questioning if it is the Tablo or the antenna.
I have no experience with the Tablo. How do the problem channels do with a TV tuner?

I've heard that the Clearstream 4Max has a narrow signal reception angle, and I'm wondering if a cheaper RCA ANT751E from Menard's would be a better option:

That version of the 751 has fewer elements than the original 751.

I'm sure it doesn't help that I have towers almost 180 degrees apart. I need to receive both from the northwest and the southeast.
The CS MAX4 does have a narrow beamwidth, but since it doesn't have a reflector, it is bi-directional.
