Features:  This installation is simple and does not require welding.  The height of the antenna is set as high as possible, need to stay away from buildings, trees or other large objects.  The ideal installation site requires a space of about 25 meters. If the space is too small, you can trim the excess hauling rope, but at each end of the antenna element and support structure, each side should not be shorter than 1 meter (3-4 feet). If it is still too long, you can shorten the antenna element. But this will reduce the efficiency of the antenna.  Widely applicable to shortwave, medium wave duty listening and QRP radio launch.  Suitable for erection of temporary places such as camping, emergency communication, etc.     Specifications:  Material: Plastic+metal.  Frequency range: 1.6-50MHz.  Impedance: 50Ω.  Power: QRP<5Watts.  Polarization mode: Horizontal.  Radiation direction: Omnidirectional.  Interface: SMA/BNC.  Antenna length: 16200mm / 637.8in.  Coaxial cable length: 6000mm / 236.2in.  Pull wire length: 6000mm / 236.2in.  Weight: 0.3Kg.     Package Included:  1 * 6M Coaxial Cable.  2 * 6M Pull Wire.  1 * 16.2M Antenna Vibrator.  1 * Balun 9:1.  1 * SMA To BNC Adapter
