Description:
- This is a 49:1 balun for the end-feeding antenna. It only needs to be equipped with a vibrator of 20 meters in length, which can naturally resonate in the four amateur bands of 7, 14, 21, and 28, and the influence of the height-changing resonance point is very small. Suitable for HAM with certain hands-on ability.
Specification:
- Condition: 100% brand new and high quality
- Product Name: End-feed antenna 49:1 balun
- Frequency: 5-35MHZ
- Standing wave: <1.5
- Loss: <1.5DB
- Withstand power: 100W PEP
Package Included:
- 1 x End-feed antenna 49:1 balun
Note:
The advantage of the end-fed balun is that the bandwidth and gain are the leading ones among natural resonance antennas. The disadvantage is that the loss is greater than that of conventional baluns, so the end-fed balun cannot be used continuously for a long time. The withstand power is 100WPEP (PEP is the peak power). In FM and data communication FT8 and other modes, it is recommended to use half the power!
