End Fed Antenna EFHW-4010-2K+ 2kW 40-10m / NO TUNER NEEDED!! / 63 feet long

Description

EFHW-4010-2K-PLUS Multi-Band End Fed Half Wave Antenna-
NO TUNER NEEDED!
EFHW-4010-2K-Plus, 2000W Multi-Band End Fed Half Wave Antenna
Improved version of the EFHW-4010-2K, now with three large cores, 2.9-inch diameter, featuring just 0.5 dB Insertion loss!
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.  Due to the 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, etc. are possible. Measured VSWR in the gallery are taken with the antenna in an inverted V shape with the center of wire at 20 feet and ends a few feet above the ground, your values could vary with way and height of installation.
NO TUNER needed!
NO counterpoise needed! (Grounding recommended*)

*Grounding at the transformer box or end of the coaxial cable 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. If the transformer box is installed high above the ground , there is no need to route the ground wire from the box, instead just ground the coaxial cable at the entrance to your home or at the station.

No guarantee or liability is either expressed or implied pertaining to damages to persons, buildings, or equipment in the installation or use of our antennas. You must
use extreme caution when working around power lines
. If the antenna were to come into contact with a voltage carrying line it could be fatal.
