Portable or Stationary Multi-Band End Fed Half Wave Antenna
This is a 200W version of popular EFHW-4010 End-Fed Half-Wave (EFHW*) antenna for 40/20/15/ and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate. It is resonant Half wave on 40m (7MHz) therefore also resonant on second, third and fourth harmonics. Due to high Impedance feed point, the antenna is less height dependent. You can put it up at 10 or 50 feet in the air without much change in VSWR values.
*This is perfect antenna for ALE HF-link stations, NVIS, MARS, ARES, EMCOMM etc.
Various installations such as horizontal, vertical, as inverted V, as inverted L, zigzag etc. are possible. Measured VSWRs in the gallery are taken with the antenna in an inverted V shape with the center of wire at 20 feet and ends at few feet above ground, your values could vary with way and height of installation.

*Grounding of the coaxial cable at radio side is recommended for protection of your equipment from an electrostatic buildup in order to prevent ESD- electrostatic discharge.
NOTE: grounding does not affect antenna tuning.
