Call 0345 2300 599The Grazioli HW10V is a high-performance half wave vertical antenna designed for serious 26 to 30MHz operation. Tunable across the 10m and 11m range, it offers a strong combination of efficiency, mechanical strength and high power handling in a more compact format than larger 5/8 wave ground plane antennas.
This base-fed 1/2 wave vertical is tuned by adjusting the whip length, with fine adjustment carried out at the base using a PTFE-insulated high voltage variable capacitor. This makes the HW10V straightforward to set up while allowing accurate tuning for your required part of the band.
The antenna is built from cold-drawn AW6063-T66 aluminium alloy tubing, chosen for its excellent strength and precision. The tube sections are manufactured with accurate diameters and wall thicknesses, giving a secure fit with minimal play. Stainless steel AISI-304 and AISI-316 hardware is used throughout for long-term outdoor durability and rust resistance.
The HW10V uses a high Q LC matching circuit, with an air-wound coil and a PTFE-insulated variable capacitor rated for very high voltage. This efficient matching system supports up to 3kW continuous power in all modes, while the DC grounded coil helps reduce static build-up and atmospheric noise.
A custom Grazioli 50 ohm UHF female connector is fitted, using PTFE insulation and a 24K gold-plated centre pin for excellent reliability. The supplied G-Max stainless steel mounting bracket provides a strong mechanical lock to the support mast, making the HW10V a robust choice for fixed station installations.

Construction Details
The HW10V uses precision AW6063-T66 aluminium alloy tube sections, with fibreglass, brass and PTFE components used in the matching and insulating areas. The vertical sections include a 42 x 2mm anchor tube, followed by 29 x 1.5mm, 25.5 x 1.5mm, 22 x 1.25mm, 19 x 1.25mm and 16 x 1.25mm tube sections. The white fibreglass insulator measures 38mm diameter with a 4.2mm wall thickness.
Installation Notes
The Grazioli HW10V should be installed on a suitable mast with clear space around the antenna. As with all high-power vertical antennas, use good quality coax, secure mechanical mounting and proper weatherproofing for the best long-term performance.
