End Fed Antenna EFHW-8010-1K-Plus 80-10m / NO TUNER NEEDED!! / 130ft long

Description

EFHW-8010-1K-Plus™ Multi-Band End Fed Half Wave Antenna
This is an End-Fed Half-Wave (EFHW*) antenna for 80/40/30/20/17/15/12 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 80m (3.5MHz) therefore also resonant on second, third, and fourth harmonics, etc.  The antenna transformer is optimized for the lowest insertion loss 3.5-30MHz featuring three stacked cores and a transformation ratio of ~56:1 (~2800:50 Ohms).
The average loss of less than 0.4dB is unmatched by any other similar transformer on the market proving our worldwide leadership in the design of high ratio-wide bandwidth RF transformers for 3-30MHz.  See the
Insertion loss chart
in gallery.
This is the smaller version of our
EFHW-8010-2K-Plus model
, see the comparison image in gallery.
Various installations such as horizontal, vertical, inverted V, 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 the way and height of installation.

*Grounding at the transformer box or end of the coaxial cable is recommended for the 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.
