Specifications Product Name 49 1 BalancerMaterial PlasticColor BlackSize 120 80 30MMFeatures 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 alsoand 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 Package Include 1x 49 1 Balancer
