Description

EFHW-7510-2K-Plus, 2000W Multi-Band End Fed Half Wave Antenna

Improved version of the EFHW-7510-2K, now with three large cores, 2.9-inch diameter, featuring just 0.5 dB Insertion loss 3-30MHz!

This is an End-Fed Half-Wave (EFHW*) antenna for 75/40/30/20/17/15/12 and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.   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.  Your VSWR values could vary with different wire configurations and height of installation.

  • NO TUNER needed!
  • NO counterpoise needed! (Grounding recommended*)
  • Frequency coverage: 3.5-30MHz
  • Resonant on 70/40/30/20/17/15/12/10m
  • Wire length ~130 feet
  • Power Handling: 2kW I.C.A.S
  • Stainless Steel hardware
  • Stealth #14 AWG XLPE black wire
  • Connector: Silver/Teflon SO-239
  • The 2K-plus model has three large stacked cores

*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.
