Outdoor antenna with radio antenna rod engagement method ---- antenna inductor connection

Keywords: radio antenna The radio takes R9700 as an example! The rod antenna on the machine retracted! With a relatively thin garden bead pen, the diameter is only slightly thicker than the antenna trolley, take 1 / 4A4 printing paper (do not use copy paper, too thin, quite poorly poor), use the thin pen to bring paper into paper Bobbin, 15cm long, fixed with double-sided non-adhesive adhesive tape. Then prepare a relatively fine 220 volt supply line, taking single stock, remove the outer kit (plastic skin or cloth), retains the insulating layer with the metal copper wire cover, about 1.5 m. This wire is wound from one end of the paper tube, and the paper tube is preorporated with the double-sided adhesive tape to help the fixed wire head, the winding process is close to the line, and the 1.5M line is all wound and stayed. A wiring head. After the entanglement, you will be uniformly wrapped on the paper tube, and the outdoor soft antenna is retracted and fixed, and finally take the pen rod inside the paper tube, even if it is done! It is very convenient to put the paper tubular tube in a completely retracted antenna tension! This paper is actually an "inductor capacitor" so that the external antenna part can select a coarse longer power cord, 5-10m is no problem, can induce a more distant or stronger signal and not overload. Generally, general broadcast signals are high frequencies, which is very easy to pass this "inductor capacitor". And many contaminated electromagnetic wave frequencies are relatively low, but it is not easy to pass this "inductor capacitor", which has played a good barrier action. At the same time, because of the spiral ring tube, it also plays a shielding effect on indoor electromagnetic contamination! Listening effect: The original 10 m wave paragraph poured V antennas to listen to noise, can't hear the show, often go upstairs to listen to the broadcast (here is another show. AM is not good. I don't want DX-AM radio. I can't complete it) In accordance with the above, it is possible to accept the radio effect. Vietnam, India. OK, I have been satisfied with the broadcast time. I don't easily receive these radios before this. I plan to find a car (AM / FM / SW) is satisfied. The DX-AM radio is a song-shaped frame antenna with a side length of 1 meter to listen to AM broadcasts for the singer (I have given me a 9kHz.) The show received in the evening is very much, it is also very clear, almost every step of the program can be listened. There is no program in the day, there is only local broadcast signals.
