Ideal for field platforms, business trips or balcony erection 5. The coil bobbin is made by die-cutting.It is made of non-manual car. The strength is very high. The coil is wound with 1.0mm stainless steel wire. All screws are made of stainless steel screws 7. The aluminum tube is sandblasted and oxidized to black, and the base is oxidized to black.
It is very beautiful and has grades. Customized 2.5 m stainless steel rod antenna.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. Frequency: can work in 8 bands of 18.104.22.168.22.214.171.124 meters (7Mhz-50Mhz) 4. Standing wave: 40m band SWR. One aluminum alloy base (anodized to black) 2. Multi-band additive coil (40m - 10m, material: nylon, Note: Adding coil for mold opening and making non-manufacturing) 3. One ground anchor, size 10×240mm (not plated to maintain good grounding) 4. Alumina tubes 4 (black), size 19 × 320mm (anode sandblasting oxidation) 5. Top 2.5 m stainless steel rod antenna 1 (customized thickened) 6. One network of 10 strands of ground wire (use it to tear open as needed, generally tear 3 strands) 7. 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. 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.
