Hi,
I am unable to receive KVUE-DT reliably, whereas other local stations (broadcasting from the same tower location) work fine.
Though my tuner (a SiliconDust HDHomeRun Dual) reports a relatively strong signal (80% signal strength, 85-100% signal quality, 100% symbol quality), this particular station glitches every 1-2 minutes (pixelation, audio drop-outs, etc.). I have no reception issues with the other stations I care about (KXAN, KLRU, KEYE, KNVA, KTBC).
Here is my TVFool signal analysis result.
And
here is the antenna I'm using (an RCA ANT751 Yagi).
Here are some pictures of the antenna mounted on my roof:

The antenna does "look through" a relatively large oak tree in my yard, as you can see from the second picture.
To verify reception issues with just this one channel, I viewed each channel for 5 minutes or so, noting no reception problems on any station except for KVUE. Also, I ran a low-level network packet loss test, which also tests for reception issues (documented
here), and this test indicated no reception errors on any channels except for KVUE. There was no network packet loss, only loss due to signal reception.
The only root cause I can come up with is interference (from the tree?), but I'd appreciate others' opinions, and I'd especially appreciate suggestions for removing the issue.
I should also note that I had previously used a different antenna (
this one) in the same location, on the same mast, and I never had reception issues on any channel. Why did I change it, you ask? Through a series of unfortunate events, beginning with this
SiliconDust issue (which I did not know about until weeks later), my HDHomeRun Dual stopped working, and I incorrectly concluded that it had died. So, I replaced it with the newer HDHomeRun Connect, which I could never get to receive a signal reliably (all channels were intermittent), having changed nothing else (i.e., same antenna, cabling, etc.).
This led to a series of hacks, including installing an antenna-mounted preamplifier, which worked great with the HDHomeRun Connect for about a day, but then stopped working (I later removed it). When I finally discovered the SiliconDust HDHomeRun Dual issue linked above, and installed the newer firmware, I was disappointed to observe that I could not reliably receive any channel (keeping in mind that this is the exact setup that previously was rock-solid, save for the new firmware and the fact that I "fussed" with the antenna to try to get the replacement HDHomeRun to work).
For better I worse, I concluded that I had damaged my existing antenna setup while playing around with the preamplifier, so I replaced it with the RCA Yagi noted above, which seemed like a better choice and was available in-store at my local Lowes.
Now, as stated originally, I can reliably receive all stations except for KVUE. Any ideas?
