GOOZEEZOO JYR4010-150W End Fed Half Wave Antenna for Ham Radio, 4 Band 10m 15m 20m 40m 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 40m, 20m, 15m, 10m. 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 150W and CW/FT8 up to 100W 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: This end-fed antenna enables quick, discreet installation in diverse environments. For optimal performance, keep it 3m ( 9.8 ft) from obstacles and 5m ( 16.4 ft) from metal surfaces. It can be mounted horizontally, vertically or diagonally with flexible balun placement, perfect for field work, home stations, backyard setups and long-term outdoor use. Its single-wire design allows fast setup between trees, poles, rooftops or masts with minimal tension. 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 ( 633814.55 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
