How can I choose a shortwave antenna?

The selection of a suitable short -wave antenna depends on many factors, including the position of the listener, what type of receiver is used and which specific broadcasts are trying to accept the listener. In general, outdoor external wire antenna provides the best income results, but this configuration may be unsuitable for listeners who have portable shortwave receivers or who live in flats or communities where restrictions forbid the erection of outdoor antennas. Short -wave radio waves are disappeared from the ionosphere of the Earth and the signal tends to be weaker, the further away from the point of transmission the listener is located. The geographical position of the listener to some extent determines which type of broadcast can be accepted and what type of antenna or receiver will provide the best results. Waves with portable receivers located in the Eastern United States. Quality, portable short -wave receiver from a renowned manufacturer will generally provide good income of most international broadcasts, with built -in, folding and whip antennaén. The next West is located the listener, the weaker the specific signals become and to increase the reception will be needed more robust antennas or receiver with greater sensitivity.

For weak signals, the reception on a portable portable can be strengthened by slightly trimming to a short piece of copper wire to the whip antenna. Some portable receivers come for this purpose with an insulated wire antenna type of reel. The outer, long wire antenna can overload the circuits of all, except the most robust and well -designed portable receivers.

For the acceptance of low-performance low-performance transmissions, outdoor, long Wire, copper antenna approximately 30-40 feet (9-12 m) in length will usually provide the best income throughout the short-wave radio spectrum. The end of the antenna closest to the listener house is packed by the guide conductor and is connected to the external connector of the receiver antenna. Because they have greater sensitivity than portable mOdla, table shortwave receivers excel in receiving weak, hard to audible stations. These specific models do not have built -in, folding antenna and usually require an external wire antenna to achieve full potential.

Many special electronics stores sell various outdoor wire antennas configurations that are designed to provide optimal income across many shortwave radio belts. They are more expensive than the universal, long -term short -wave antenna, but generally provide excellent results. These professional antennas are produced specifically for use with shortwave boarding board receivers.

For listeners living in apartments or communities with outdoor antennas restrictions, the short -wave antenna can be a good choice. Active antennas are designed for use inside and come up with a telescopic whip antenna that allows amplification of the signal built into the unit. Active antennas can be used with stolate receiversLike portable receivers equipped with a suitable external connector that receives an active antenna connection. In general, the models of active antennas with a higher price generally provide the best results.
