HF20A Shortwave 1.5-30MHz Full-Band Antenna Dead-Zone-Free Antenna Shortwave Radio Outdoor Antenna
Specification:
1. Maximum input power: 1000W
2. Recommended operating power:50W
3. Operating frequency range:0.5¨C30 MHz
4. Typical SWR: below 2.0 under proper installation conditions
5. Standard radiator length:20 meters
6. Radiator material:multi-strand copper wire, approx. 1.0¨C1.5 mm
7. Ground stakes: 2 stainless steel stakes (not included by default, user may supply as needed)
Installation Notes:
1. For fixed installation on a roof or similar location, the antenna can be set up using a direct connection between the two ends of the antenna system, depending on the installation environment.
2. In outdoor use, grounding conditions may affect performance. A stable installation and good connection points can help improve operating results.
3. If the installation area does not allow grounding stakes, alternative configurations may be used based on site conditions.
4. Antenna height and installation angle may influence radiation characteristics and communication range.
5. The radiator length has limited impact on SWR, while overall installation and environment may affect performance.
6. For long-term outdoor use, it is recommended to protect metal parts from corrosion and moisture.
