So this is great, I cracked open all 3 of my Roku ultra devices and removed the 2 antennae in each, closed it back up and it works great! Not some models may have 3 antennas but my older ultras only had 2 each.
I'd rate this as easy, all that's needed is a nylon spudger, philips screwdriver and optionally some electrical tape.
All I did is wiggle the metal antennae at their 2 connection points to fatigue the metal until it snaps off. I covered the terminal points with electrical tape just in case and re assembled.
Note if you have micro SD cards you will want to remove them first before starting, as they get in the way of removing the case.

Having a background in electronics, I guessed that removing the WiFi and Bluetooth antennas would
be the easiest way to stop RF output without harming any other circuitry- so I used some hefty wire
cutters to cut them off and for added measure cut the pcb connection to nearby broadcast chips
with an exacto knife.
No harm done, so both Rokus that were modified work fine with no measurable rf output. You do
take a risk bricking your media player, but for us worth it. So stay grounded and don't touch any pins
on chips if unnecessary.
