JYR8010-400W End Fed Half Wave Antenna for Ham Radio, 400W Shortwave Radio Antenna 8 Band 10m 12m 15m 17m 20m 30m 40m 80m Long Wire Antenna, 1:64 Balun No Tuning Great for POTA/SOTA

Multiband & Low SWR
An end fed antenna is a multiband HF antenna engineered for smooth, reliable operation across 10m / 12m / 15m / 17m / 20m / 30m / 40m / 80m. This half-wave end fed antenna delivers consistently low SWR across all supported bands, enabling efficient signal transmission and reception without constant adjustment. Fully compatible with Yaesu, Icom, Xiegu, Kenwood, and most HF transceivers, it offers outstanding flexibility for a wide range of amateur radio applications ^^
No Tuning Required: Handles SSB up to 400W and CW up to 300W FT8 up to 150W for reliable HF operation. The integrated 1:49 / 1:64 impedance transformer enables efficient multi-band performance without an external antenna tuner in most setups, simplifying installation and helping both beginners and experienced ham operators get on the air quickly ^^
Flexible Hanging & Easy Deployment: An end fed ham antenna designed for fast and flexible installation. For optimal performance, keep the antenna 3m ( 9.8 ft) away from objects (including foliage) and 5m ( 16.4 ft) from metal surfaces. It can be deployed horizontally, vertically, or diagonally, with flexible balun placementmaking it ideal for field work, backyard setups, home stations, and long-term outdoor use. Perfect for POTA activations, temporary field deployments, long-term camping, and overlandingsupporting reliable contacts around the world ^^
Rugged & Reliable Construction: Crafted with an ABS shell, the 1:64 Balun Antenna offers durability and excellent craftsmanship. Heavy-gauge antenna wire, a reinforced end insulator, secure clamping system, and a sealed housing ensure long-term durability and stable performance in diverse weather conditions. For best longevity, inspect the installation and guy rope every 6 months (typical service life 35 years) ^^ Innovative Natural Cooling
Design (GOOZEEZOO Exclusive): Built for long-term outdoor operation, the antenna features a waterproof M-J connector, UV-resistant housing, and large ferrite magnetic core (633820 mm) for stable impedance transformation. The air-convection cooling enclosure draws cool air from the bottom and releases heat from the top, helping maintain stable performance during extended transmissions
