Description

1.6MHZ - 50 MHz shortwave antenna LW1650 portable shortwave antenna Frequency range: 1.6 to 50 MHz 50 Ω impedance: Power: QRP < 5 watts Polarization mode: level Radiation direction: omnidirectional Interface: SMA/BNC Antenna length: 16.2 m Weight: 0.3 kg Kit includes: 1: coaxial cable is 6 m 2: stay 6 m x 2 3:16.2 m antenna vibrator 4: Balun 9:1 5: SMA To BNC connector 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. Set up on the roof is a good choice. Because floor of reinforced concrete structure, can absorb the cover part of the various buildings electrical produces all kinds of jamming signal, and the surrounding environment is relatively empty is conducive to the antenna signal. Set up between the two buildings is not a good choice. Because building is reinforced concrete structure, can keep out absorption signal. Buildings of all kinds of electrical appliances will produce all kinds of jamming signal radiation out through the window, be antenna to receive Shipment quantity: 1 Set
