   antenna is based on any number of parameters: specifically, the frequency or band of frequencies, location, directivity, and intended power range. This paper discusses some of the more important aspects of the End Fed Half Wave (EFHW) dipole antenna. The frequency band is HF (40 meters), and the intended power is 100 watts.

   End-fed half wave antennas are best for temporary antennas using low power and batteries, far from power mains and noise sources. They are more prone for problems near noise sources or consumer gear, and can easily exceed FCC RF exposure limits with surprising low power levels.

   The EFHW (End-Fed Half-Wave) antenna has become popular with portable operators because of its mechanical simplicity. The antenna is a half-wavelength dipole fed at one end. (See the End-fed Zepp section of the Single-Band MF and HF Antennas chapter.)

   Unlike center fed Dipole, the EFHW antenna can be used on both odd and even multiples or harmonics. For example, the multiple of 3.55MHz times 2,3,4,5,6,7,8 will produce

   This is exactly the convenience the end-fed half-wave antenna (EFHWA) offers. It does not require an extensive ground like a big ferrous vehicle body, only a short counterpoise wire. It is a favorite of Summits-On-The-Air (SOTA) activators and ARES/RACES that roll it up into a backpack or toss it in an emergency go kit.
