Luxury Version Pac-12 Portable Shortwave Antenna JPC-12 Shortwave Antenna Outdoor Balcony Stand AntennaAntenna performance parameters:1. Carrying weight is about 1.4Kg2. 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 40.30.20.17.15.12.10.6 meters (7Mhz-50Mhz)4. Impedance: 50Ω5. Carrying power: 100W6. Standing wave: 40m band SWRPacking List:1. 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 cable with 2.5mm plug (adjustable band)7. 1 set of hooked screws for adjusting the band8. One network of 10 strands of ground wire (use it as needed to tear open, generally tear 3 strands)9. Special cloth packageNote: The antenna does not include the -7 base, clamps, adapters, and feeders used for balcony erection.Please see the detailed description below!!!Antenna use precautions:1 Put the connecting ring of the ground net directly on the screw of the ground anchor and screw it onto the base. Note that the washer is tightened between the ground anchor and the ground net.Then there is the connection seat--shield (to prevent the base from being scratched when the vibrator is attached)--four-section aluminum tube--sensing coil--rod antenna2. The adjusting screw with hook should not be tightened too much, because the coil is made of tinned copper wire, which is soft and too tight, then the coil is deformed.3. The opening side of the adjusting screw with hook is facing the rod antenna. When the adjusting screw is not used in the 40-meter band, it is recommended to take it off to prevent the short-circuit coil.4. Don't circle the feeders, you must turn the feeders all on, otherwise it will affect the adjustment of standing waves.5. When the standing wave is adjusted, if there is a talent meter, 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 coilIf there is no talent, use the station's own standing wave meter, set in FM, AM or RTTY
