Tip 1: How to choose a street antenna

For high-quality reception of a television signal it is necessary to use street antenna. To select the option that is appropriate for your TV receiver and its location, you should examine the capabilities of each type of equipment.

Instructions

The design of the antenna depends on whichthe television signal you want to receive: terrestrial or satellite. If there is a television tower in the village or within it, you can take local channels here - it's terrestrial television. It is enough to install the antenna in the direction of the telecentre, connect it with a cable to your TV and watch the broadcasts. To have access to most domestic and foreign programs, you will need to receive the signal with the help of satellite equipment.

Pick up the antenna of the airway reception To receiveimages of local programs need a meter antenna, decimeter or all-wave reception. Determine the priority of the channels. For example, you like transfers on NTV, MTV, and the rest are not interesting. Consult a specialist and measure the level of the television signals at your location. Based on the results of measurements, find out the type of antenna in which reception of the "picture" will be of high quality. For example, in the presence of interference or the complete absence of a decimetre wave signal, install a DTSM antenna. For reception of a qualitative image of all channels the model of all-wave reception will approach.

Select the antenna design.Watch the numerous television channels by installing satellite dishes. By design, they can be grouped into several types: direct focus, offset, spherical, flat, portable. The first - have a parabolic shape and concentrate the signal, not allowing it to dissipate. Such a plate is large and requires a remote bracket for installation. Mostly, this equipment is used for professional reception of a satellite signal.

Select a home antennaFor residentialapartment buildings and country cottages fit a spherical, offset, flattened antenna or equipment such as a "street lamp". For example, the offset design is placed vertically on the wall of the house or on the balcony, it does not accumulate snow, water and dirt creating interference. In order not to disturb the architectural appearance of the building, choose a flat antenna for your home receiver - it does not stand out against the wall and allows you to enjoy the television of excellent quality. Take a satellite signal and on the nature. In order not to miss the favorite transmission, turn on the portable antenna, and it will be tuned to the desired channel within 5 minutes.

Tip 2: How to choose an antenna

If you decide to choose a good satelliteantenna, then pay attention to the main parameters that will directly affect the quality of the received signal, and therefore either justify or do not justify the means enclosed in the antenna. To select a good quality antenna, follow the simple recommendations given in this manual.

Instructions

First of all, determine, in whichthe receiving satellite system will operate the antenna. Before choosing an antenna, answer a few questions: which channels are you interested in; whether it is possible to arrange the antenna so that the signal of the satellite does not overlap with foreign objects; you want to watch one satellite or several; how much you are willing to spend on the antenna.

Select the size of the future antenna. The diameter of your antenna will depend on the power of the received signal. That is, choose the diameter of the antenna, depending on the geographical location in which you are located. It is best to contact the company whose services you want to use and find out exactly which antenna diameter is needed to receive the signal in your area. The following are approximate signal power and antenna diameter ratios. Power (dbW) 53 - diameter (m) - 0.648 - o, 845 - 1.142 - 1.540 - 1.8

Select the shape of the future antenna. Antennas are offset and direct focal. Prymofokusnye - this is an ordinary plate, the converter of which is fixed in its center with the help of spokes. In winter, a mirror of such an antenna can cause ice and snow to fall, this will greatly worsen the reception quality of the signal. Offset antennas are antennas whose focus is shifted down from the mirror, so they can be easily cleaned.

Correctly choose the type of antenna suspension. The azimuth suspension is one on which the antenna is rigidly fixed, with this suspension the antenna is tuned to a single satellite. Polar is more expensive and provides tuning to several satellites.

Choose the material from which to makeantenna. The most popular material is aluminum, it is light and cheap, but soft, it is easy to damage and the deformation of such antennas has a very bad effect on the reception quality of the signal. Antennas made of steel are stronger and cheaper, but they are heavy and corroded, so when selecting such an antenna, attention to the quality of its coloring. Plastic - very light, but to such a fast snow sticks. Mesh - light and comfortable, they are almost invisible and they do not spoil the landscape, but the quality of signal reception from them leaves much to be desired.

In the event that you select an antenna forcar, it is better to prefer a passive television antenna, to install it better on the roof or in the wing. Choose the antennas correctly and enjoy good image quality.
