Aerial Connectors
Aerial connectors are a low cost and low quality analog connector found on almost all TV's. They are easy to use and can be found as a default connector on almost all audio and video components, but their poor signal quality mean that they may eventually be replaced by the higher quality HDMI connector.
The standard TV aerial plug takes two forms:
Belling-Lee or IEC 169-2 connector
This is the traditional coaxial antenna connector for TV sets and FM-radio receivers in Europe and the Asia Pacific region. The oldest coaxial RF connector still commonly used today, it was invented at Belling & Lee Ltd in Enfield, England, around 1922, at the time of the first BBC broadcasts. It was originally only intended for medium frequency broadcasts, and is unsuitable for modern VHF and UHF TV frequencies. Due to its design this connector is prone to signal reflection & distortion, and can be particularly problematic with digital signals.
F Connector
Used primarily in North America, this connector is also found on Cable and satellite TV connections. The key advantage of the F connector over the Belling Lee design is that it has similar resistance to the 75-ohm antenna cable it is mated with, reducing the amount of reflection and distortion. The F connector is also know by the less inspiring name - IEC 60169-24.
