END-FED ZIBER Antenna with power handling of 150w SSB and 100w on Digital modes like FT8!
How can it be called a long wire antenna? Do you just pull a thread? Do not! Strictly speaking, that's just. The name of the antenna should depend on the operating frequency. If the length of the antenna is exactly half the wavelength, it is called a Ziber antenna, also called a terminal-fed dipole antenna. An antenna whose length is greater than one wavelength is called a long-line antenna. A more strict definition can be summarized as: an antenna whose length is greater than one wavelength and an integer multiple of a half-wavelength can be called a long-line antenna. So when we use the same antenna to work in different frequency bands, the name of the antenna is different? For convenience, we call the antenna that works in the low frequency band as a long-line antenna.
It is designed with M connector. Large magnetic ring (loss is minimized) plus PCB are used to fix balun.

Everything comes in the bag ready to go. Made a strain relief for the feedline and pulled it up with the line provided.
I received mine in the mail today and set it up temporarily in the backyard about 5 to 6 feet above the ground. Running 10 watts PEP from an Icom 703, I was able to check into the Aurora Net on 40 meters, and work a couple of POTA activations on 20 meters. It's not designed for 80 meters and, unsurprisingly, the SWR is sky high on that band. However, the Icom 703 internal tuner was able to match it on 80 meters where I was able to check into the BC Public Service Net and talk to some friends of mine. I wouldn't try this using high power, though, as it might fry the balun. The antenna seems well made and, mounted higher and using more power, I'm sure you could work the world on it. SWR is acceptable on the bands it was designed for and my IC-703's tuner could get a match on 17 and 12 meters, too. It would not tune it on 30 or 60 meters, though. I'm quite happy with the antenna after an afternoon of portable qrp usage. Recommended.
