There's probably* no harm in trying to unplug the antenna board RCA cable from the tuner and connecting an RCA to F-type coax adapter.
*Some TVs are hot chassis and there could be 120V on the shield of the tuner and it's antenna... Before connecting the 2 I would measure the AC and DC voltage between them and if either is over 10V I'd avoid connecting them directly.

Thanks
Good point. I actually pretty sure it's a hot chassis and shouldn't do that. I think that's why the antenna block isolates the RF through CR101 and CR102
Is there maybe some way around it, like copying the decoupling capacitor on my own?
This is the power plug input. Pretty sure that's hot.
