Product Description
If you are a QRPer, or will the wild Communications lovers ; If you want to have a highly efficient full-size antenna to get better QSO experience, then Gypsy (Gipsy) 7-30MHz horizontal dipole antenna winding type (DIPOLE ) must be suitable for you. It was wild born, to pay tribute to the efficiency , fighting for every decibel !
[Features]
1 full-size half-wave horizontal dipole antenna , the classic high-efficiency antenna.
2 Carbon Wei Balun fully waterproof , all-weather combat .
Three commonly used four -band (7/14/21/28-29MHz) preset mark , with the bobbin easily adjust the switching frequency .
4 special canvas pouch , size is very small after admission .
[Principle , adjustment method ]
Gypsy (Gipsy) 7-30MHz level winding type dipole antenna is a dipole antenna from a single horizontal band evolved , the two ends of each transducer with a special bobbin , in use, bobbin equivalent to a transducer wire coil, and this induction coil open circuit in the electrical principle equivalent ( note not loading coils , but similar across the two arms of the choke balun dipole antenna as ) . So when you switch to a different operating frequencies , simply release the bobbin oscillator different length cable. The antenna has four common 7,14,21,28-29MHz sleeve marker bands preset the transducer line and indicated on the bobbin casing in different colors represented by the band , the actual very easy to use . Casing color corresponding to the band as follows:
7MHZ - green (GREEN), on the bobbin abbreviated written as (GN = 7MHz);
14MHz - Yellow (YELLOW), on the bobbin abbreviated as (YE = 14MHz);
21MHz - blue (BLUE), abbreviated in the bobbin (BU = 21MHz);
28-29MHz - red (RED), abbreviated in the bobbin (RD = 28-29MHz).
About Carbon Wei Balun : Yes, this product balun using carbon fiber tube , not the surface decorative stickers . Some friends have doubts about it , the carbon fiber material has a certain conductivity, to do with it balun enclosure seems inappropriate. In fact, Barron is two main coupling path , one coupling between lines , one magnetic coupling. When using a conductive material as the balun enclosure , through the rational design after layout is totally no problem. If you also want to further explore , you can refer to the following military Barron cast aluminum housing design .
