Unfortunately a spot check isn't enough. If it dips below for a second every 2-3 minutes, that would cause it too. There's an android app that can monitor it in close to real time, so you can watch it for a few minutes and see if it dips - https://play.google.com/store/apps/details?id=com.zaren&hl=en_US
Thanks for the suggestions, though I think I figured out what the problems were. I know the antenna range is a bit exaggerated, but I live with 20 miles of the broadcast antennas, so I figured even if 85 miles was an overestimate, it should still work. The amplifier with the antenna is bad. I swapped it out and now my signal strength is 100%.
By split 4 times, I mean one 4-way splitter was used with a -7.5 dB loss on each leg. I switched it out for a two way splitter (with only a -3.5 dB loss for each) so only the two active TV in my home have signal. I figured this couldn't hurt.
This is the app I'm using. It displays Signal Strength, SNR Quality and SYM Quality on a 0-100 scale.
Now, the solution. As I said, using a different amplifier helped with the signal strength (according to the app mentioned above), but I was still receiving the weak signal and disconnect messages. My Shield TV is wireless, but I have an AC router and it's connection has never been an issue. The problem I found was with the Live Channels app on Android TV. When using the Live Channels app, you can choose your channel sources. Mine was showing two options for live TV, the built-in network TV tuner (beta), and HDHomerun Input (since I have the HDHomerun app installed). I've always used the network TV tuner because it allows me to use DVR functions. Recently I noticed that the first channel I tune to worked, as does the second. But after that, I would get "weak signal" on a previously crystal clear channel, and the "all tuners in use" message in the HDHomerun app. I believe you are correct. I think the built-in network TV tuner is locking each tuner in the Extend and not releasing it when changing channels. I switched my input source to HDHomerun Input, everything seems to be working fine.
Thanks for your help.
It's almost certainly the server being unable to keep up with transcoding for the rokus, mixed with possible signal issues. Try watching it on your desktop with another window open to watch the signals, both from http://my.hdhomerun.com/ Alternatively, if you have an android device you can try watching the signals with the signal meter app: https://play.google.com/store/apps/details?id=com.zaren&hl=en On the pc it will be a direct feed from the hdhomerun, which should allow you to rule out plex and transcoding completely. Make sure your signals and playback in this way are flawless before you try adding plex into the mix.
Also not all tuners are created equally. What worked for your Hauppauge may not work for your hdhomerun.
Are you sure the antenna is pointed at 218 degrees? Next time you're on the roof, use your iPhone compass app or install an Android compass app to find out the direction you're facing it.
Also, while on the roof, use the Signal GH app (for iPhone) or the Signal Meter app (for Android), which will tell you the signal level on your HDHR, so that you can fine-tune adjust the antenna pointing while on the roof:

hdhomerun has an app to measure signal strength

You (or someone else) can use this in real time to see what moving the antenna does to the signal strength for the channels you are interested in
Please post a link to your TVFool report.
There's a free Android HDHomerun Signal Meter app that shows signal strength.
The hdhomerun system log doesn't track strength, and Plex doesn't see that information. For the app: https://play.google.com/store/apps/details?id=com.zaren&hl=en
I used the Android 'Hdhomerun Signal Meter' app to fine tune mine at the antenna. I know this is too late for you but may help others. https://play.google.com/store/apps/details?id=com.zaren

additionally, KODI should be able to pick up that stream. there's definitely an Android app, and maybe there's a Windows install available too.
