The processing technology of vibrator aluminum tube has been improved. At the same time, it has been changed from 28cm to 32cm. The connecting seat has been changed from the original aluminum part to copper part The mini-buddipole antenna is a miniature portable antenna designed for field mobile communications. Completely is made according to the original standard, can work in 2,6,10,12,15,17,20,30,40 meters, contraction after 34.5 cm long, two \ oscillator expanded for 6 meters (4.8 m), the size of the package to: 37 cm * 23 cm, weight 1.8 kg, easy to carry erection convenient, after hand as long as a support bar and feeder, can set up to use, all the other parts are disposed of for you In addition, if you like the way GP is set up, you can also buy a ground grid and ground anchor to form a set of fine pac-12, so that a set of antennas is equivalent to a set of jpc-7 and pac-12, very economic, super value Ground net, ground anchor this shop has sale Impedance 50 ohm standing wave 1.0-1.2 The coil skeleton and base are made of moulded, not made by hand. The material is nylon. The strength is very high and there is no need to worry about damage. The coil is now wound with 1.0mm 304 stainless steel wire, which has higher strength and overcomes the weakness of the tinned copper wire The aluminum tube is sandblasted and oxidized to black, which is very beautiful Equipped with special black portable cloth bag, perfect protection antenna, easy to carry, more class. It is easy and fast, and can be set up by one person in 3 minutes Notes for antenna use:1. The assembly sequence of each oscillator of the antenna is as follows: connecting seat – two aluminum tubes – inductive coil – pull rod antenna2. If you use a talent meter with low transmission power, do not coil the feeder into a circle, but open all the feeders, otherwise the adjustment of standing wave will be affected, and the talent meter with higher power will not matter3. The first turn is on the side of the antenna near the pull rod. Count from the side with the screw of the fixed coil, and do not count the half turn with the screw5. When adjusting standing wave, under the condition of the instrument, first find the lowest point of standing wave, see whether the resonance frequency is high or low, if the resonance frequency is high, the antenna is short, want to lengthen the pull rod antenna or increase the number of inductance coil, shorten the pull rod antenna or reduce the number of inductance coilIt is suggested to adjust the inductor coil and pull rod antenna on one side of the black line first instead of adjusting the oscillators on both sidesIf you don’t have a talent meter, use the station’s own standing-wave meter, set it in FM, AM or RTTY mode, reduce the transmission power to about 10 watts, press the launch button, adjust the radio frequency knob, find the minimum point of standing wave on each frequency band, see the resonance frequency, and then use the appeal method to adjust Reference data:40m band: 7.050- the red coil starts the 5th turn from the aluminum tube side, and the black coil also starts the 10th turn from the aluminum tube side. Note: the half circle with one screw does not count. The antenna of the pull rod on both sides is pulled out 7.050 standing wave 1.2-1.520-meter band: 14.270-red wire coil starts from one side of the pull rod antenna for a count of 5 turns, and all 10 sections of the pull rod antenna are pulled outThe black wire coil also counted the 11th turn from one side of the pull rod antenna, and all 10 sections of the pull rod antenna were pulled out at 8cm Standing wave 1.0 to 1.215 m band: 21.300 red wire coil 3 turns, pull rod antenna 10The black wire coil has 3 turns, and the tie rod antenna has 9 +11cm 21.300 standing wave 1.210 m band: 10 pull rod antennasThe other pull rod antenna 10 retracts to about 7cmStanding wave 1.2 (without inductive coil) List of accessories:Connection base (material: nylon)Multi-band coils (40m-10m, material: nylon) x2pcsAlumina tube x4pcs (black), 19×320mmTop 2.5m stainless steel tie rod antenna x1pcs (customized and thickened)Rubber head screw x2pcsErect positive V copper connectors x2pcsNote: the new antenna will be replaced by the new magnetic ring barron instead of the plug -3 American feederSpecial black hand-held cloth bag x1pcs, shape specification 37*23Special adapter x1pcs made of aluminum for connecting the tripod
