In this nicely done video, Stu (VK5STU) offers a cautionary tale of what happens when an end-fed antenna installation doesn't meet expectations. Eventually, Stu overcame the obstacles and got his antenna working better than before. Here are some of his comments: Putting up an end fed antenna at home after removing it for some repair work.

A Brief Synopsis of the Antenna Features & characteristics In this article, I will try to cover various aspects of the End-Fed Half-Wave (EFHW) wire antenna including, its geometry, characteristics, performance parameters, the influence of the practical surrounding environment where the antenna might be deployed, as well as transmission line interfacing.

Once I had the antenna operating on 80, 40, and 20 meters, I realized I could easily add a 30/15-meter end-fed antenna. I simply tied a 2-foot length of nylon cord to the Spiderbeam mast about 3/4 of the way up, then tied a length of 18-gauge bare stranded wire to the free end, running it back down to my station. I then adjusted the wire length for
End Fed Terminated Antennas
As the name suggests, an "end-fed" antenna is just that: the radiating element is fed at one of its ends, instead of somewhere in-between its two ends (i.e., center-fed like a standard dipole, or off-center-fed). A special case of this, is the End-Fed Half-Wave (EFHW) antenna. Obviously, an EFHW antenna has a "half-wave" length only at one.

Thoughts from Frank and Fern End Fed Antenna Review
The key to end fed antenna success is the matching network interface between the long wire antenna and the coax feed line and feed line choke at the transceiver. Palomar Engineers employs a dual core matching system that offers wide bandwidth (1-61 MHz), 500 watt PEP rating, and a connection for a counterpoise or ground if desired..

The Single Wire End Fed Antenna is probably the simplest antenna to use. But when you start looking around, you find that no one can agree on what length to use. Some say any length will work, some stress odd multiples of 1/4 wavelength, while others lean toward even multiples of 1/2 wavelengths. Some say design for the lowest frequency you.

In the case of the end fed antenna it is an unbalance antenna so it is possible to connect you unbalance coaxial cable to an unbalance antenna but now you have another issue, an impedance mismatch. The end fed wire has a high impedance, usually several hundred ohms, while the coaxial feedline has a much lower 50 ohm impedance.

When researching the EFHW and random-wire antennas, you will find transformers recommended with impedance ratios of 9:1 (turns ratio of 3:1) to 64:1 (turns ratio of 8:1). To pick the right turns ratio, you need to know the antenna feed point impedance. Most end-fed antennas will have a feed point impedance of 1000 to 5000 Ω.

With the "end fed" antenna, this is coupled to the coax shield (bottom primary windings). In practice this current will run over the outside of the coaxial cable. It may be hard for some (including me) to imagine a coaxial cable can be seen as a cable with three conductors. The center core, the inside of the shield and thirdly the outside.
