The Atari RF cable I got from eBay was exactly what I needed. No noise, clear picture, looks fantastic. Such a simple solution, I have no idea what all those "easy ColecoVision hook up!" tutorials on YouTube are talking about with using cheap RCA cables and leftover coax cables. Thank you, you saved my ColecoVision!!

AH! I think this is the issue. All it came with from eBay was a coax cable with a coax adaptor screwed onto it, so I used a generic RCA cable (as shown by many YouTube hook-up-your-CV videos). I've ordered a shielded RF Atari cable and will see if that does the trick. Thank you!

Channel 4 is noisier than 3.

No, I'm using an RF adapter. It's the one that was attached to the coax cable that was included with the system when it arrived. I'd thought of trying a newer RF adapter as well, as I'm not sure how old this one is. I'll try getting inside the system and see what happens, thanks for the tips.

I searched other threads on this topic, but the situations they describe seem different than what I'm experiencing. I bought a ColecoVision off of eBay and it's very functional (hooked up via RCA/coaxial to a Vizio HDTV), but the picture is consistently covered in a layer of noise. I've tried multiple RCA cables and multiple coax cables, and have cleaned the RCA ports, but nothing seems to change the noisiness of the image; wiggling or adjusting the cables or the cartridges doesn't make it either better or worse. I'm using the adapter that came with it; would that contribute to the snowy image? Any thoughts on how to clean up the picture? It's not unusable, but not great at all.
