Topteng JPC-12 7MHz-50MHz 100W 8-Band HF Portable Shortwave GP Antenna QRP passend für Ham Radio

- ❣️Shrinkage and Erection Length: The shrinkage length is about 34.5cm, and the erection length is about 410cm, providing flexible usage in different scenarios. This design allows for easy storage when not in use and sufficient length for optimal performance during operation, meeting the needs of various application environments.
- ❣️Multi-Band Operation: Can work in 8 bands (7mhz-50mhz) at 40, 30, 20, 17, 15, 12, 10, 6 meters. This wide frequency coverage enables the product to adapt to different communication requirements across multiple bands, enhancing its versatility and practicality for users who need to switch between various frequency ranges.
- ❣️Longitudinal Wave Performance: 40m swr band <1.3, other bands can be adjusted to 1.1. The excellent standing wave ratio ensures efficient signal transmission and reception, reducing signal loss and improving communication quality. This parameter reflects the product's stable and reliable performance in different frequency bands.
- ❣️Slider Reference Data: Close to the aluminum tube passend für 4 turns of 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 the side of the rod antenna 6 turns and pulls back about 20cm, foot wave 1.1-1.3; 21.4 Aluminum tube and 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 back about half a section, the standing wave is 1.2.
- ❣️Ground Grid Installation and Standing Wave Adjustment: Put the ground grid connection ring directly on the screw of the ground anchor and screw it into the base, then link base-four aluminum tubes-loading coil-rod antenna; in standing wave adjustment, with a talent analyzer, find the lowest standing wave point to check resonance frequency, adjust antenna length or loading coil turns accordingly.
