Portable wire antennas
Portable wire antennas is a simple suite, contains all the necessary components. Is a simple and effective rapid deployment of shortwave antenna. With light weight, small size, easy to carry and set up easily. Is widely used in short wave, medium wave of duty to listen to and QRP radio emission. Suitable for camping, emergency communications, and other places of temporary construction. (if you want to permanently fixed construction need to strengthen the strength of the anchor and waterproof Balun)
This simple installation without welding. The height of antenna erection as high as possible. Need to stay away from buildings, trees or other large objects. The ideal erection site need a space of about 25 meters. If the space is small, can trim excess traction rope, but in the antenna oscillator and the ends of the support structure, each side shall not be shorter than 1 meter (3 to 4 feet). If it's too long, can shorten the antenna oscillator. But it will reduce the efficiency of the antenna.
It is a good choice to set up on the roof. Because the reinforced concrete structure of the floor, will block the absorption of some buildings in a variety of electrical appliances generated by a variety of interference signals, and the surrounding environment is relatively open to facilitate the antenna to receive signals.
It is not a good choice to set up between the two buildings. Because the building is reinforced concrete structure, will block the absorption signal. Building a variety of electrical appliances generated by a variety of interference signals will be emitted through the window, the antenna received
The following figure is used in the antenna set up in the park, then the RTL.SDR + UpConverter full-band SDR software radio receiver received the wave broadcast signal.
