The Grazioli Antennas FE10V is a high-performance 5/8-wave vertical antenna for the 10 and 11 meter bands, tunable from 26 to 30 MHz. Designed for serious amateur radio and CB operators, it features a low radiation angle for excellent long-distance performance and is engineered to withstand extremely high power levels up to 5 kW CW continuous duty. With a total height of 7.63 m (25.0 ft) and a rugged 6 kg (13.2 lb) construction, the FE10V combines strong electrical performance with exceptional mechanical durability.

The Grazioli Antennas FE10V is a high-performance 5/8-wave vertical antenna for the 10 and 11 meter bands, tunable from 26 to 30 MHz. Designed for serious amateur radio and CB operators, it features a low radiation angle for excellent long-distance performance and is engineered to withstand extremely high power levels up to 5 kW CW continuous duty. With a total height of 7.63 m (25.0 ft) and a rugged 6 kg (13.2 lb) construction, the FE10V combines strong electrical performance with exceptional mechanical durability.
The High-Q Coil: A key feature of the FE10V is its generously sized air-wound matching coil. Suspended without metal cores and optimized with a length-to-diameter ratio of 1.3, wide turn spacing, and carefully selected conductor dimensions, the coil achieves an impressive Q factor of approximately 2500 at 28 MHz. This design minimizes RF losses, maximizes efficiency, and contributes to the antenna's ability to handle very high power levels. The coil is also DC-grounded, helping reduce atmospheric noise and static buildup.
Custom 50 Ohm UHF Connector: Unlike standard commercial SO-239 connectors, the FE10V uses a proprietary connector designed and manufactured by Grazioli Antennas. It provides a true 50 Ohm impedance and is rated for operation up to 500 MHz. Built to withstand continuous 5 kW operation at 30 MHz, the connector features a nickel-plated CW614N brass body, a 24K gold-plated center pin, a four-fin insulating support for reliable contact pressure, and a PTFE insulator with excellent electrical and thermal properties. A protective elastomer hood helps prevent water and moisture intrusion.
Heavy-Duty Mounting System: The mounting bracket is manufactured from 2.5 mm thick AISI 304 stainless steel and secures to the antenna using a clamp-style locking system for exceptional mechanical strength. Mast attachment is provided by AISI 304 stainless steel M6 V-bolts and high-profile nuts that simplify installation and tightening while ensuring long-term durability in outdoor environments
