I got
this thing when I first got my RV, which of course didn't have the TV in it anymore (unused 2016!) - but I have two 28" computer monitors sitting around.
The monitor fit perfectly, and that box took over all the TV / channel functions, gave me a remote control, and even lets me DVR stuff to a USB stick so I can pause and fast forward! Aux out to the RV head unit for sound, and HDMI out to the computer monitor. For $35 I was kinda shocked at the capabilities.
It also has an amplifier function, but disables itself when I use amp built in to the antenna / coax plate.
The thing also has a signal meter / % indicator for each channel, auto-program etc etc.
This could be a really easy and cheap way to amp the antenna, give yourself a nice signal meter, and throw in some other features as well.
