1: 1 high power balun
Withstand power: SSB <2000W
Data transmission, CW <1000W
AM, FM, SFK <500W
Frequency range: 1 ~ 30mhz
Standing wave: 1.03 (1mhz), 1.22 (30mhz)
The balun is a current type. It adopts imported 50-3 Teflon silver-plated fully shielded feeder and an oversized magnetic ring 63x38x14mm. The shell is UV-resistant resin (estimated no problem for 10 years of outdoor use). It has a connector waterproof function. At 2KW, the high-frequency voltage is up to about 900V, and at 100W, the high-frequency voltage is also about 200V. Assuming that when the connector enters the water, under the action of 900V voltage, the water will electrolyze, oxidize the joint, smoke, and generate poor contact.
