REZ Antenna Systems Scout-XF 40-Meter Loading Coils

REZ Antenna Systems Scout‑XF 40‑Meter Loading Coils allow you to elevate your 40‑meter portable HF performance with precision‑built components engineered for rugged field use. Designed specifically to pair with the Scout‑XF mounting base and a telescopic whip, these coils form the core of a compact 40‑meter vertical antenna system ideal for portable, field, and emergency operations.

Built with 14‑gauge enameled copper wire and a CNC‑machined Delrin body, the Scout‑XF coils deliver long‑term durability, and excellent weather resistance in demanding outdoor environments.

The SC‑4017 loading coil is optimized for use with a 17‑foot telescopic whip, while the SC‑4025 coil is intended for a 25‑foot whip, giving operators flexibility to choose the configuration that best fits their deployment style.

Featuring 3/8‑24 threading on both the top and bottom for broad accessory compatibility—and power‑rated at 500W PEP SSB / 200W CW‑DIG—the Scout‑XF coils provide rugged, dependable performance wherever your operations take you.

Note – The Scout-XF Mounting Base and Telescopic Whips are sold separately
