Omnidirectional Vertical Antenna – Versatile & Easy to Install
Perfect for operators with limited space or those seeking a high-performance, hassle-free solution, our 10.6 m vertical antenna covers the 1.8 to 50 MHz range. It comes with a built-in 1:4 Unun featuring a Teflon-insulated female PL connector for maximum reliability.
No traps or radials are needed, making it ideal for restricted installations. Easy to set up and maintenance-free, it works perfectly close to the ground (on a support less than 1 m high). Compatible with built-in automatic tuners, it offers a low SWR curve across multiple bands, reducing the need for an external tuner.
Built to last, it features a 35 mm diameter, 2 mm thick base tube, ensuring strength and durability. It handles up to 400 W PEP in SSB and provides omnidirectional radiation, ideal for all-around coverage.
This antenna is versatile, supporting both low-impedance (coax) and high-impedance (twin-lead or ladder line) feeds.
A proven classic — undefeated since 1999 !
