HF End Fed antenna EFHW-7510-1kW-ICAS 130ft long

This is the first EFHW antenna we introduced back in 2015, and we are proud to celebrate its 10th anniversary. Over the years, we've made subtle enhancements to ensure top performance: the transformer has been refined, and the antenna wire has been upgraded to durable 16-gauge XLPE stealth wire.

In 2016, this antenna was reviewed by ARRL QST Magazine, and you can read the detailed review here. EFHW-7510-1KW-ICAS Multi-Band End Fed Half-Wave Antenna.

The EFHW-7510-1KW-ICAS is a premium End-Fed Half-Wave (EFHW) antenna designed for seamless multi-band operation across the 7 0/40/30/20/17/15/12/10m bands. Unlike many end-fed antennas on the market, this model requires no antenna tuner, thanks to its resonance on 80m (3.5 MHz) and its harmonics 2nd, 3rd, 4th, etc. No Tuner Required : Fully resonant across multiple bands.

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.

Can be deployed in configurations such as horizontal, vertical, inverted V, or inverted L. Constructed with durable, black #16 AWG XLPE wire for a low-visibility, weather-resistant installation. Equipped with stainless steel hardware for longevity.

Frequency Range : 3.5-30 MHz. 250W for digital modes such as FT8. Transformer : MEF-330-1KW-ICAS, optimized for 3-30 MHz. Grounding 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. Typical 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 Use. This antenna is ideal for ALE HF-Link, NVIS, MARS, ARES, EMCOMM, and similar applications.

It's suitable for both temporary and permanent installations, ensuring reliable communication in critical scenarios.
