Roku Stick Interfering with OTA TV Reception.

My Roku 3810 Stick appears to be interfering with OTA (Over the Air) TV Reception.

I posted earlier on this yet cannot find the thread. I realize OTA is no longer a popular choice, but I prefer the uncompressed PQ.

Anyone use a work around such as a remote on/off switch for the USB or wall power?

Is it the position or the fact it's plugged in at all? If it's the position, you could experiment with an HDMI extension cable.
Power supplies themselves sometimes create noise, might want to try a different one just to see.

The Roku's proximity to the set causing the interference you mean?

Right now just using a USB pigtail to tap into the set's USB port.

True in both cases, I had a CRT set about < 4 feet away using a converter box that appeared unaffected by it. ?now that I goit rid of the CRT I'm using the flat screen's tuner, so I'm revisiting this problem, I noted this a couple years back but never looked into it to far

As a few shifting back to antennas I could think that this could be a common problem, right now I reach back & un[plug the USB Id rather use a switch, ports wear out.

My OTA approach is a network tuner (Silicondust), which is there for me more as a backup than anything as I rarely use it, but it works great through both Roku and Firestick.
All OTA TV is compressed. The more subchannels, the more compression. ATSC 3.0 uses better compression than ATSC 1.0. Watching via a streaming provider can be better if they are getting a fiber feed from the stations master control before the start mixing for the transmitter.
You can buy an inexpensive HDMI coupler to attach to any HDMI cable and then a stick to get it far away from the TV.
Reach out to Roku about the issue, it shouldn't be blasting that much RF that it interferes with the HDMI signal...strikes that something is foo with the Roku 3810 Stick.
I'm a bit behind on this....

This is a strange one, as I have now relocated the Roku with a heavy shielded extension cable about 2 - 3 feet away from the set and am now using a USB multi Charger as a supply for the Roku, using the Roku supply did not seem to make a difference, yet moving the stick away helped especially on UHF, VHF High (as RF 8 & 10 is used in my area) still seems to jump a bit when the Roku is powered.

I watched the promo video on this, so is this a OTA tuner or what? I;m assuming it is but interfaces the TV via a router or WiFi, not the tuner. & this uses an app on a Roku?

I don't have a Smartphone, don't I care to watch TV on a tablet, my Internet speed is fine for what I have though my antenna hookup is at the other end of my dwelling from my router, I'm still intrigued, but how can this be an advantage to me? The promo says to "download an app to your device" is there an app available via the Roku that interfaces this all to the TV?

The stick plugs right into the main board on most sets, my other unit sits away from the set at least, though I don't notice it there as I don't watch OTA on that set. Perhaps I should be switching the units around.
Update, as I'm am using extensions & external USB supplies now...

I unplugged the USB power to my Ruko Stick & it was a difference from a heavily pixelated RF signals on VHF Hi (RF10 & & RF 8) to a very watchable signal on both on a day where both my Local & Semi local (28 miles & 42 miles) signals were coming in very good, so it may or just plain may not make a difference depending on the days reception.

It is making a difference, but still having the stick powered @ 3 feet is compromising a signa, esp on VHF.l
It may be overly sensitive TV tuner circuitry, either not well grounded or shielded. Possibly a signal amp on the antenna might help.
Or maybe just a defective Roku throwing out a lot of noise.

I find my Youtube TV provides better video quality than the NYC OTA signal.

I actually have a 12dB amp on the antenna, with my antenna located in the attic above the set. The amp a one piece powered in the room but about 4 feet away from Ruko, rather than the normal 2 piece design, so it may not be optimal.

Did another test the other day, my CBS Affiliate broadcasts on RF10 with a repeater on RF20, With the Roku plugged directly into the TV (but powered by a remote hub), RF10 was heavily pixelated, & unwatchable, where RF20 was watchable, but had dropouts where the screen would go black. Testing with the 3' HDMI extention, RF10 was watchable with occasional pixelization, RF20 still had the dropouts, but was a bit better. Next I unplugged the Ruko from the USB power hub (essentially disabling it), resulted in a much better RF10, with very occasional small pixelization, & RF20 being a bit better, though still had an occasional black screen dropout.

So yes, agreeing with your statement, the Roku is interfering with the TV in some way shape or form, but depending on the level of interference I'm willing to accept, I can just unplug the Roku power now... next step may be shielding Roku in a metal box. As these devices are designed to plug directly into the set.

Are you speaking of Signal strength vs Picture Quality? I do note that at times I will have no issues with a Sub channel in 480p, yet on the same RF channel, the main 720/1080p is heavily pixelated or non watchable due to signal compression.

You referencing Pay YouTube service? I once got a decent analog OTA signal in my area, over the years the & after the 2009 transition, digital signal became worse as the Band auctions progressed & the band got smaller. My OTA stations in my DMA caters to the western & southern areas, where I'm in the Northeast area that is under the Canadian protection area (which doesn't help), I have an RF10 in Canada I imagine that's creating havoc with my local RF10 (thus they are currently using 4 repeaters along with their main channel in my area)
