Review on Enhance Signal Quality with Parts Express Push-On 'F' Type Balun by David Norwood

Mine doesn't have the plastic trim around the metal balun that plugs into the 75 ohm input on the TV but still connects easily. This is for an old computer that needs a video modulator with 300 ohm jacks to connect to the TV. Definitely brings back the experience of the early 80's, full of noise and fuzzy resolution which is in no way related to this device but because of the video modulator (or switcher as they were called) itself! If you're looking for a cheap way to hook up old Atari, Intellivision, ColecoVision, TI, Commodore or other gaming systems or home computers from the late 70's and early 80's, this should help.
