With the RF output your mileage will vary.

First thing is to never use cheap audio cable to hook up the RCA output of
the CoCo into the RF input of your TV.

I have used for the longest time a video grade short run of RG-6 coax cable
(12 to 24 inches long) fitted with an RCA-to-F female adapter on one end
(coax patches usually come with F connectors on both ends). This setup has
provided me with a clean very pleasing experience using my CoCo 1 F board
with a regular 9" Color TV.

If the proper coax cable doesn't fix your TV monitor view then its time to
check on using a different TV set (it can happen their RF input is messed
up) and at worst case the CoCo's output.
