Will it work? Yes.
Will it work good? I have my doubts.
You may have better luck using” a 40 year old UHF antenna and a simple rabbit ears for my TV’s, getting about 30+ OTA HDTV stations.”
Q: Will it electrocute me if I push the paperclip in while the tv is on?
A: The antenna jack is not powered, so there should be little or no danger of getting shocked by adding a simple wire to the antenna jack. The only danger is doing damage to the antenna jack inserting too large of wire gauge of wire into the jack.
