Brief introduction: Brand New & High Quality Portable Horizontal Dipole Antenna! If you are a QRPer, or will the wild Communications lovers ; If you want to have an efficient full-size antenna to get better QSO experience, then Gypsy (Gipsy) 7-30MHz winding Horizontal dipole antenna (DIPOLE) must be suitable for you.
It was wild born, to pay tribute to the efficiency of every decibel battle! Full-size half-wave dipole antenna level , the classic high efficiency antenna. Carbon fiber Balun fully waterproof , all-weather combat. Common quad-band (7/14/21/28-29MHz) pre- marked , with the bobbin easily adjust the switching frequency. Special canvas pouch , the volume is very small after admission.
The working principle, adjusting method: Gypsy (Gipsy) 7 to 30 MHZ winding type horizontal dipole antenna, have evolved from single band horizontal dipole antenna, the ends of their two vibrator, respectively, with a special winding frame, in use, winding frame oscillator wire is equivalent to an inductance coil, and the inductance coil on the electrical principle of equivalent of open circuit (note not loading coil, but similar jumper in the choke of dipole antenna barron arms). So when the working frequency of different switch, need only in winding on a wire rack to release the vibrator of the different length of line. This antenna has 7, 14, 21, 28 and 29 MHZ four commonly used on the stator line spectrum of sleeve tag preset, and a different color as indicated in the winding frame casing, represented by the frequency of actual use is very convenient. Sleeve bands corresponding to the color as follows. 7MHZ - Green (GREEN), written as an abbreviation in the bobbin (GN = 7MHz); 14MHz - Yellow (YELLOW), abbreviated as the bobbin (YE = 14MHz); 21MHz - blue (BLUE), abbreviated as the bobbin (BU = 21MHz); 28-29MHz - Red (RED), the bobbin is abbreviated as (RD = 28-29MHz).
Technical Parameters: Frequency: 7-30MHz continuously adjustable SWR: 1.2 Input Impedance: 50 Power: 100W PEP Vibrator Material Irradiator: 20AWG tinned copper Teflon Socket Type Outlet: SL16 (ie M Female) Balun: 1:1 balanced - unbalanced magnet Balun Cross Weight: 400g. 1 x 7-30MHz Horizontal Dipole Antenna + Balun.
