160–80–40m End Fed Antenna by GØCSK
At the Junction Box , coax inner connects to the antenna wire (blue) and braid connects to the brown wire and ground spike.

I built the circuit into a plastic and waterproof electrical box that I had purchased at The Home Depot. The box is made by Carlon and is 26 cubic inches in size. I used 1/4" stainless steel hardware for the antenna and ground connections and a small terminal strip to mount the components.

Klik voor vergrotingEnd-Fed Half-Wave Antenna & Tuner by VK2ZAY
For the on-going 2007 ARNSW Homebrew Group Challenge work I needed a simple 80 metre antenna. As a home-unit resident the size of a full half-wave is pretty impractical, but I decided to try it so I had a base-line to compare future shortened verticals to.

Klik voor vergrotingLong wire antenna for portable operations by VK6YSF
With the view to establish a quick and easy multi-band antenna deployment for portable and camping operations a simple long wire antenna with an earth or earth plus counterpoise arrangement with a 9:1 voltage unun including a tuner or simply with a tuner is one possible solution.

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 (center-fed like a dipole, or off-center-fed).

Klik voor vergrotingSlope antenna for HF high band (14-50MHz) by JA1HWO
This antenna is a slightly improved version of the one that was raised instantly for a contest.
Of course, we can't expect much gain because it's just a wire, but it covers the high band of HF, so it's quite convenient and occasionally used.

The W3EDP end fed wire antenna lends itself readily to QRP and portable operation. A simple matching unit is needed to couple the wire to the rig and a counterpoise is required for some bands, ...
