    Features:

    1. This balun is a 49:1 balun dedicated to end-fed antennas. It only needs to be equipped with a 20-meter-long vibrator (remember that it is a standard 20-meter) to resonate naturally in the four amateur bands of 7, 14, 21, and 28, and the height change has little effect on the resonance point. It is very suitable for HAMs with certain hands-on skills (you can make a 20-meter-long vibrator yourself). The magnetic ring is a specially magnetic ring, and the M seat is also and extended (the short M seat is still loose when the M male head is screwed to the bottom). The magnetic ring is fixed with PCB and works stably and reliably for a long time.
    2. Main parameters: 5-35MHZ, standing wave less than 1.5, insertion loss less than 1.5DB, withstand power 100W PEP (SSB) (the baluns have passed the 30-minute continuous transmission test safely, and the parameters are all real.)
    3. Note: The advantage of end-fed balun is that its bandwidth and gain are both NO:~~1 in natural resonant antennas. The disadvantage is that its loss is greater than that of conventional baluns. Therefore, end-fed baluns cannot be used continuously for a long time. The withstand power is 100WPEP (PEP is the peak power). Data communication 100W is twice the peak power. Remember to use halved power in FM and data communication FT8 modes!
