Description:

This balun is a 49:1 balun for the end-feeding antenna. It only needs to be equipped with a 20-meter-long vibrator (remember to be the standard 20 m) to naturally resonate in the four amateur bands of 7, 14, 21, and 28, and the height-changing resonance The influence of the point is very small, it is very suitable for the HAM with certain hands-on ability (you can make a 20-meter long vibrator yourself), the magnetic ring is a custom-made magnetic ring, and the M-seat is also customized and lengthened (the short M-seat M-head) Screwed to the end or loose), the magnetic ring is fixed by PCB for long-term work and is stable and reliable.

Main parameters:

5-35MHz standing wave less than 1.5 insertion loss less than 1.5DB withstand power 100W PEP (SSB) (Balun is safely passed through the continuous emission test for up to 30 minutes, the parameters are real standards, we will never consider the standard 150W).

Note:

The advantage of the end-feeding balun is that the bandwidth and gain are both NO:~~1 in the natural resonant antenna. The disadvantage is that the loss is greater than the conventional balun. Therefore, the end-feeding balun cannot be used continuously for a long time, and the withstand power is 100WPEP (PEP). Is the peak power) Data communication 100W is double the peak power, remember to use the FM and data communication FT8 mode power halved!

Package Includes:

1 x End-feed Antenna 49 :1 Balun
