The coil bobbin is made by die-cutting. The material is nylon, non-ppr pipe is made by hand. The strength is very high. The coil is now wound with 1.0mm 304 stainless steel wire, which has higher strength and overcomes the deformation of tinned copper wire. The weakness is that all the screws are made of stainless steel screws, and the vibrator aluminum tube is sandblasted and oxidized into black. Note that it is not a simple aluminum rod and two screws. This is an aluminum tube. Even if it is erected horizontally, the sag is very high. Small, not as drooping as an aluminum rod is very serious. The base is oxidized to black, and the custom 2.5 m stainless steel rod antenna is used for higher strength and the communication efficiency is greatly improved.
1- Light weight, small size and easy to carry
2- can work easily in multiple bands
3- Easy to set up and fast, one person can be set up in 3 minutes
4- Very suitable for field stand, business trip or balcony erection
5- The coil bobbin is made by die-cutting. It is made of non-manual car. The material is nylon. The strength is very high. The coil is wound with 1.0mm stainless steel wire.
6- All screws are made of stainless steel screws
7- Aluminum tube blasted into black, the base is oxidized to black, very beautiful and graded
8- Customized 2.5 m stainless steel rod antenna
Reference data when using the slide adjuster: 14 mega-slider position is close to the rod-shaped antenna on the side of the rod antenna and retracted by about 20 cm, 7 megabytes is close to the side of the aluminum tube, and the rod is retracted by about 10 cm.
Antenna performance parameters:
1. Carrying weight is about 1.4Kg
2. The length of the contraction is about 34.5cm, and the length of the erection is about 410cm.
3. Frequency: can work in 8 bands of 18.104.22.168.22.214.171.124 meters (7Mhz-50Mhz)
4. Impedance: 50Î©
5. Carrying power: 100W
6. Standing wave: 40m band SWR<1.3, other bands can be adjusted to 1.1
1 x Aluminum Alloy Base (anodized to black)
1 x Multi-band Additive Coil (40m - 10m, material: nylon, Note: Adding coil for mold opening and making non-manufacturing)
1 x Ground Anchor 10Ã—240mm (not plated to maintain good grounding)
4 x Alumina Tubes size 19 Ã— 320mm (anode sandblasting oxidation)
1 x Top 2.5m Stainless Steel Rod Antenna 1 ( thickened)
1 x Network of 10 Strands of Ground Wire (use it to tear open as needed, generally tear 3 strands)
1 x Special Cloth Package
Note: There is no feeder, but also to save energy, no paper manual.
1 Put the connecting ring of the ground net directly on the screw of the ground anchor and screw it onto the base. Then it is the connecting seat--four-section aluminum tube--adding coil--rod antenna
2. In the case of standing wave adjustment, if there is a talent indicator, first find the lowest point of the standing wave and see if the resonant frequency is high or low. If the resonant frequency is high, the antenna is short, and the rod antenna should be lengthened or increased. Increase the number of turns of the coil, shorten the rod antenna or reduce the number of turns of the coil
If there is no talent, use the station's own standing wave meter, set in FM, AM or RTTY mode, adjust the transmission power to about 10 watts, press the launch button, adjust the radio frequency knob, find in each frequency band. The minimum point of the standing wave, look at the level of the resonant frequency, and then use the appeal method to adjust
3. When the ground net is used, tear 3-4 pieces off. Adjust the angle of the ground net to change the impedance of the antenna.
Slider Adjuster Reference Data:
7 megabytes in 4 turns on the side of the aluminum tube, the rod is retracted to about 10cm, standing wave 1.1-1.3
The 14-megan slider position is close to the side of the rod antenna and the 6-turn lever is retracted by about 20cm. The standing wave is 1.1-1.3.
21.4 with 4 aluminum tubes plus rod antenna 7 knots + 10cm, standing wave 1.1-1.3
29.6 only use the rod antenna, all pull out and retract half a section, standing wave 1.2
Note: The above parameters may vary slightly depending on the environment. You can fine tune it according to the actual situation you use.
