Multi Band HF Shortwave GP Outdoor Slide Regulator Antenna QRP For Ham Radio New
New and high quality - Made of high quality material, durable - Package weight: about 1.35kg Package size: 36224cm - The contracted length is about 34.5cm, and the erected length is about 410cm - Frequency: Can work in 8 frequency bands (7mhz-50mhz) at 40.30.20 17.15.12.10.6 meters.) - Rolling power: 100w - Longitudinal wave: 40m swr band. Close to the aluminum tube and turn 4 times 7mb, the pull rod retracts about 10cm, and the foot wave is 1.1-1.3 The position of the 14mb slider is close to side of the telescopic antenna for 6 turns and then pulled about 20cm. Foot wave 1.1-1.3 21.4 aluminum tube 4-pole antenna, 7-10cm, vertical wave 1.1-1.3 29.6 As long as the antenna is pulled out from the pole, everyone pulls it back about half a knot, and the standing wave is 1.2. 1 Put the ground grid connection ring directly on the screw of the ground anchor and screw it into the base.
Then there is the link base - four aluminum tubes - loading coil - whip antenna. In the case of standing wave adjustment, if you have a gifted analyzer, find the lowest point of the standing wave to see whether the resonance frequency is high or low. If the resonant frequency is high, the antenna is short. Lengthen the whip antenna or increase the number of turns of the loading coil.
If the resonance frequency is low, shorten the whip antenna or reduce the number of turns of the loading coil. The minimum point of the standing wave depends on the resonant frequency, and then use the above method to adjust 3. When using the ground net, tear off 3-4 pieces. The antenna impedance can be changed by adjusting the angle of the ground grid. 1 x Aluminum alloy base (anodized to black) 1 x Multi-Band Loading Coil 40m - 10m; Material: Nylon. Note: Loading Coils are processed by mold opening instead of handmade 1 x Ground Anchor 10 x 240 mm (unplated for good grounding) 4 x aluminum oxide tubes black 19 x 320 mm (anodized) 1 x 2.5 m stainless steel telescopic antenna (can be customized) 1 x 10-strand ground wire (tear as needed when using; generally tear 3 strands) 1 x cloth bag. Due to various factors such as display brightness and light brightness, the actual color of the product may be slightly different from the website picture.
