Digital TV has redefined the way we watch TV. It offers crystal clear audio and video. Its narrow bandwidth signal transmission allows telecasters to fit more channels in a certain range of frequencies, thereby, allowing you to view more channels than you could on analogue TVs. It also offers you picture on demand and a host of other facilities like recording one channel on the set top box while you are viewing another program. Unlike analogue models where transmission towers beamed signals to the antenna, their digital counterparts receive signals from a satellite via a dish antenna, connected to the TV.

Parts of the digital TV antenna
The antenna of the digital TV is parabolic in shape and has a better signal reception ability than yagi antennas, generally used for analogue telecasts. The diameter of the dish is proportional to the signal frequency. An area where the signal frequency is low requires a larger diameter dish and vice versa. Signals received from the satellite reflect from the dish on to the driven element (dipole or horn), containing a low noise block down converter, which amplifies the signal and sends it to the decoder in the set top box via a RG-6 coaxial cable. The decoder decrypts the encoded signal received from the signal before passing it on to the digital TV.

Setting up the antenna properly
You need to set up and adjust the antenna properly so that it faces the satellite. You should ensure that the F/D ratio is in the range of 0.38 to 0.5 for optimum signal reception. The reception quality depends on the ratio, with 0.5 providing the best signal reception. In this formula, `F’ refers to the `focal length’ (the distance between the center of the dish and the driven element) and `D’ stands for the `diameter’ of the parabolic dish. Rain and hailstorms block proper flow of signals from the satellite to the antenna, resulting in distorted/ hazy pictures, and degraded sound quality. However, you can tackle this problem by ensuring an F/D ratio of 0.5. If necessary, request your family members to check the signal quality while changing the horizontal and vertical alignment of the dish. Using an insulated RG-6 coaxial cable, having an electrical resistance of 75 ohms, and containing a foil shielding between the core and outer conductor prevents distortion of the signal from magnetic interference.

Are you unable to understand these technical terms?
Are you puzzled by these technical terms? Even a slight misalignment of your digital TV antenna can result in poor quality audio and video. It is better to contact Jims Antennas and seek his help to set up and configure your digital TV antenna.


What Does A Plumber Do?
