This End fed antenna is unique, as it is resonant on 4 bands without the need of a tuner and also operate WARC bands with a tuner. With a power handling of 1 kW, they will handle enough power for the majority of Amateurs.
EFHW-4010 Multiband End Fed Half Wave Antenna 63ft (19.2m) long
NO TUNER needed for 4 main bands!
Resonant on 40/20/15/10m (WARC bands with Tuner)
This is an 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 a resonant Half wave on 40m (7MHz) therefore also resonant on second, third and fourth harmonics, 20m (14MHz), 15m (21MHz) and 10m (28MHz). The antenna could be used with 100W on WARC bands too, where measured VSWR is less than 4:1. Due 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.
Various installations such as horizontal, vertical, as inverted V, as inverted L, zigzag etc. are possible. Measured VSWR in the gallery are taken with an antenna in an inverted V shape with the center of wire at 20 feet and ends a few feet above ground, your values could vary with way and height of installation.
NO TUNER needed!
NO counterpoise needed! (Grounding recommended)
