Shortwave Antenna

Although shortwave antennas are not like ordinary radio, they are used to receive signals from specific radio stations which choose to operate on shortwave bands. As with the majority of antennas, you are best off putting the shortwave version outside and attached at an adequate height. You should also ensure that they are not in close proximity to any power lines. A popular place to mount this type of antenna is typically on rooftops. A shortwave antenna that is placed in a good location with well matched frequencies will give you a very strong signal. The reason for the name is because the very first ever radio transmissions were conducted at far lower frequencies, and therefore produced far longer waves.

There are numerous types of antenna and they have different noise values. A loop antenna is generally designed for indoor use and provides an extremely low noise value. As long as they are correctly shielded, a small or large loop antenna should be far less susceptible to localized noise. It is best that you know that the vertical antennas are the most susceptible to localized noise, and therefore you should try and arrange the wire in such a way that it will eventually improve the overall characteristics of this piece of equipment.

The most commonly used antenna for shortwave listeners will be the telescopic version. However you can easily obtain far better results with a longer wire if you can find an antenna connector on your radio. For an indoor antenna you are best off placing it in the attic or high up on a wall. The best shortwave receivers and radios use a coaxial antenna. This will actually provide shielding and can help to prevent the picking up of any electrical noise. If you are not using a commercially made indoor antenna, you will find that many Shortwave Antenna designs need to be placed outside of the building to produce the best results.

There are many different types of Shortwave Antenna used nowadays however the most common are:

Homemade Shortwave Antennas – You should initially make the antenna wire and the ground wire of equal quarter-wave length when using certain frequencies, although you can make homemade antennas either directional or non-directional.

Directional Antennas – These are typically made for 2 way communications, such as a transmitter and a receiver. The most common directional antennas include the Yagi/beam, vertical loops, Quad and the log periodic. These types of antenna will usually give you a better performance as interference from outside and unwanted sources will be dramatically reduced.

Yagi/Beam Antenna – These are typically used as a TV antenna, although if you use them at a lower frequency and at larger wavelengths, they will automatically become larger. This will, therefore, mean you have to reduce the total number of elements contained within this type of antenna.

HF Antenna – Although their frequency varies, an HF antenna are in very much the same range as shortwave bands. You will actually find the term HF is most commonly used in ham radio gear or for commercial equipment. These types of antenna have great designs and are also ideal for transmitting.

If you are in no mood to experiment, you can actually purchase a shortwave antenna kit. They should cover several shortwave bands and are great when you just don’t have the time or inclination, or if you simply want to use your radio. These kits will usually come with a Shortwave Antenna wire and an antenna coax.

We then have shortwave radio which has a range of 3 to 30 MHz. However it is important to understand that a short wavelength will typically have a corresponding high frequency. There has always been this relationship between wavelength and frequency. As mentioned, the reason for the name shortwave radio is merely because the wavelengths produced and used are far shorter than the longer wavelengths used in early radio broadcast. You will find that “high frequency” is actually just an alternate name for shortwave radio.

Shortwave bands have a range of 2.3 to 26.1 MHZ and there are actually 13 different international broadcast bands. These are 11, 13, 15, 16, 19, 22, 25, 31, 41, 49, 60, 75 and finally 90 metres. You should find that although shortwave does overlap with high and medium frequency, the majority of shortwave listeners are most likely listening to the AM or LW band on their radio.
