Just a quick tour of the My-Antennas 80-10EFHW up and now running at the QTH.
An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground ...

Utah Valley amateur Radio Club's Half Wave End Fed Antenna Detailed Build Instructions for the 80-10 end-fed half-wave antenna with 49:1 unun: Noji-Article-80-10-EF-HW.pdf
3 wrz 2017 · Here is a video showing the new MFJ end fed HF antenna. What can I say, it works.. I didn't remember to bring my analyzer today, so the next video i will sweep it and show results at a different location.
Oggies have been urging me to try the MyAntennas EFHW-80-10 antenna, so I purchased one with channel funds. It looks solid and I will put it up this coming w...
The 80-10-JR-KW consists of the two components shown in Figure 1 – the antenna wire and an impedance transformer. Designed to be used on 80, 40, 20, 15, and 10 meters, the EFHW antenna wire is approximately one half-wavelength long on 40 meters with a coil and extension that add 80 meter operation.
