EFHW-4010-1KW-ICAS Multi-Band End Fed Half-Wave AntennaThe EFHW-4010-1KW-ICAS is a premium End-Fed Half-Wave (EFHW) antenna designed for seamless multi-band operation across the 40/20/15/10m bands. Unlike many end-fed antennas on the market, this model requires no antenna tuner, thanks to its resonance on 40m (7 MHz) and its harmonics (2nd, 3rd, 4th, etc.).Features and Advantages No Tuner Required: Fully resonant across multiple bands. High-Efficiency Transformer:Designed with two FT-240 (2.4inch dia.) stacked cores for minimal insertion loss.Transformation ratio of ~56:1 (~2800:50 Ohms).Optimized for 3.5–30 MHz with an unmatched average loss of less than 0.6 dB—a benchmark in the market for RF transformers.Worldwide leader in high-ratio, wide-bandwidth transformer design by E73M. Flexible Installations:Can be deployed in configurations such as horizontal, vertical, inverted V, or inverted L. Stealth Design:Constructed with durable, black #18 AWG wire for a low-visibility, weather-resistant installation.Equipped with stainless steel hardware for longevity.Technical SpecificationsFrequency Range:7–30 MHz.Resonant Bands: 40/20/15/10m.Power Handling:1 kW I.C.A.S. for voice modes.250W for digital modes such as FT8.Wire Length: ~63 feet.Connector: Silver/Teflon SO-239.Transformer: EFHW-330-1KW-ICAS, optimized for 3–30 MHz.Grounding RecommendationsGrounding the coaxial cable at the home’s entry point is highly recommended to protect equipment from electrostatic buildup and prevent electrostatic discharge (ESD).If the transformer box is mounted high above the ground, grounding at the box is unnecessary—ground the coaxial cable instead.Note: Grounding does not affect antenna tuning.SWR PerformanceTypical SWR readings are better than 2:1 when mounted 25–30 feet above ground and fed with 50 feet of RG8X coaxial cable.Perfect for Emergency and Professional UseThis antenna is ideal for ALE HF-Link, NVIS, MARS, ARES, EMCOMM, and similar applications.
