5 Band EFHW Antenna 80m-10m|49:1 End Fed Half Wave

If you need a simple, efficient 5 band HF antenna, then this modified End Fed Half Wave Antenna from Hayden (VK4YE) is for you.

The antenna measures 25 meters long (82 feet) and uses a counterpoise and a 49:1 impedance matching network.  A wide range antenna transmatch (i.e. "tuner") should be able to help keep SWR within limits.

Here some observations from Hayden (VK4YE):

Here are my experiments and modifications with an EFHW (end-fed half wave) based on the VK4YE design, testing, 80m loading coil, the coax counterpoise, and the common mode toroids. This allows a antenna for smaller spaces and backyards.
