Multiband, No-Tuner Ready: Engineered for seamless operation across the 40m, 20m, 15m, and 10m bands, this multiband end fed antenna features a precision 1:49/1:64 transformer. It delivers consistently low SWR across all bands, allowing you to bypass external tuners for a true plug-and-play experience.

Reliable Power Handling: Perfectly suited for portable and low-power operations, this end fed antenna is rated for 150W SSB, 120W CW, and 80W FT8. It utilizes a high-performance ferrite core (63×38×14.55 mm) to ensure stable impedance transformation and reliable signal integrity.

Exclusive Air-Convection Cooling: To maintain performance during extended transmissions, the housing features a specialized air-convection design. By drawing cool air from the base and exhausting heat through the top, this passive cooling system effectively dissipates heat, preventing performance degradation.

Flexible Deployment Options: Designed for versatility, this 20m antenna supports horizontal, vertical, or sloped configurations. It is an ideal, low-profile solution for restricted urban spaces, home stations, or rapid-deployment scenarios like POTA activations and overlanding.

Rugged, All-Weather Construction: Crafted with a UV-resistant, waterproof ABS enclosure and a secure, heavy-gauge wire system, this half-wave end-fed antenna is built to endure harsh outdoor conditions. With an expected service life of 3–5 years, it is a durable investment; we recommend a routine inspection of guy ropes and connections every 6 months.
