Open aerial and method of joint of radio antenna lever

Radio with R 9700 for exemple! The telescopic antenna on machine is all and retractile! Compare fine and long garden with bead shaft, the diameter compares thick little of aerial pull rod slightly only, the printing paper that takes 1/4A4 (do not use duplicating paper, too thin, the difference that hold out a gender) , become scroll paper bobbin with fine shaft, grow 15cm, with double-faced heal of adhesive tape of not dry glue is fixed. Prepare a power supply cord of finer 220 bend over next, take sheet, eliminate coat layer (plastic skin or cloth are covered) , reservation and core of metallic copper silk wrap the insulation layer that Fu contacts, length about 1.5m. Undertake this electrical wiring voluble since the one aspect of the matter of paper bobbin, paper tube termination is stuck beforehand double-faced stick adhesive plaster to secure electrical wiring head in order to help, twine a process tighten between central line and line lean, the line of 1.5m tangles entirely and put apart receives thrum. Even bag goes up to pester a transparent not dry adhesive plaster in paper line canister again after tangling, the wiring head of put apart has been received with the soft antenna outdoor and had secured, take out the shaft inside paper line canister finally, so far aerial considers do good! When using, paper line bobbin covers completely retractile aerial pull rod to go up, very convenient!

  The joint means that the article uses is actually " inductance capacitance " , such outside it is OK to receive aerial share the selection is wider longer power supply cord, 5, 10m is no problem, can the signal with more distant or stronger reaction also won't overload, ordinary broadcast signal is taller frequency, pass this very easily " inductance capacitance " . And the electromagnetic wave frequency of a lot of contamination is lower, pass this not easily instead " inductance capacitance " , rose to cut off very well action. At the same time because be make it helix annulus manages account, had the screen effect that pollutes to indoor electromagnetism again!

Listen to the effect:
10 meters of wave band are received to pour V antenna to come to to listen to noise outside before, do not listen to a program at all, often hear broadcast to upstairs (here FM program. AM is not Orphean. Think DX-AM radio is bad to cannot be finished) , will make according to above paragraphs, received broadcasting station result still can be accepted. Vietnam, India. Russia is wide wait for me to broadcast in its time satisfaction is received, before this I get these broadcasting station not easily. The plan seeks opportunity of a car (AM/FM/SW) satisfied so. DX-AM radio is engine of song happy car (medium wave pace grows to had changed 9KHZ to me) did an edge to grow the casing form antenna for 1 meter to listen to AM broadcast so. In the late evening when received program is exceedingly much, very clear also, almost every condition is chief have the program that can listen. There is not what program by day the hookup signal that has this locality only.
