Why do you have to line up transmitting and receiving television aerials?
Antennas are normally directive, receiving more signal, or transmitting more signal in one direction than another. To ensure that the best performance is obtained, it is necessary to align or point the antenna in the right direction. This antenna alignment or orientation is an key part of any antenna installation.
Why can’t I get a signal from my TV aerial?
First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already. If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.
What’s the difference between ITV and BBC?
The two main differences during the ‘glory years’ – i.e the ’90s, when I was was watching, because I am the only human being that matters on this wretched planet – was that in between shows, CBBC had a live studio with gurning, bouncing, pneumatically-shaking presenters, whereas CITV just had a friendly, disembodied …
What is a loop TV aerial?
The Loop is an indoor directional TV aerial. The compact size occupies minimal space, providing a subtle solution where space is limited. Features: Receives all available digital terrestrial TV signals. High quality, durable and robust construction.
What does D aerial mean?
For digital TV reception – you get either a good picture or no picture at all. The digital aerials have built in filters to lower noise and improve picture quality. The analog signal is transmitted directly to the TV while the digital signal needs to be decoded first.
How do you check if a TV aerial is working?
Test Your TV Aerial Cable Another way to check the TV aerial is to take the TV to a socket that you are sure is working correctly and perform a test. If the TV can get a signal and identify the channels on another socket, you can rest assured that your TV is fine.

What is the difference between a loop antenna and a folded dipole antenna?
The electric dipole has a much smaller radiation resistance than the magnetic loop, but more important is the ratio of antenna currents. For an insulated electric dipole, it is given by the capacitive current through the sheath; for a loop antenna, the current is determined by the loop inductance and applied voltage.
