Grazioli MV7 multiband vertical antenna with ground-plane radials, shown against clear sky – premium HF/VHF antenna stocked by Radioworld UK

Grazioli MV7 Multiband Vertical Antenna HF 40, 20, 17, 15, 12, 10m + VHF 6m


The Grazioli MV7 is a high‑performance, no‑compromise multiband vertical antenna designed for serious HF and 6m operators. Built without traps or lossy matching transformers, the MV7 delivers maximum efficiency, exceptional bandwidth, and outstanding power handling across all supported bands. Every component reflects Grazioli’s engineering philosophy: precision machining, premium materials, and rugged mechanical integrity.

Perfect for operators who want a single, robust, wide‑coverage antenna with true long‑term reliability.


Key Features

  • True 1/4‑wave Ground Plane Vertical covering HF 40–10m + VHF 6m

  • Base‑fed design for low‑loss operation

  • Massive power handling:

    • 1500W SSB on 40m

    • Up to 3kW on all other bands

  • Total height: 8.97m

  • Weight: 8.5kg

  • Premium AW6063‑T66 aluminium throughout

  • CNC‑machined components for perfect mechanical alignment

  • 304/316 stainless steel hardware for long, corrosion‑free service

  • Dual‑Band Folded Counterpoise (DBFC) system for efficient 40m operation

  • No traps, no loading coils on upper bands — maximum radiating efficiency

  • Custom high‑power UHF connector (true 50Ω, gold‑plated centre pin)

  • Includes FAIR‑RITE FT240‑43 toroid for building a high‑performance choke

  • Made in Italy with full serial‑number traceability


Construction & Materials

  • Heavy‑duty 42mm → 19mm tapered aluminium radiating element

  • Four 2.7m ground‑plane radials

  • CNC‑machined aluminium and thermoplastic support arms

  • AISl‑316 clamps and AISl‑304 U‑bolts

  • PTFE‑insulated, gold‑plated RF connector

  • Designed for long‑term outdoor installation in harsh environments


Performance

The MV7 is engineered for operators who demand efficiency and stability across multiple bands.

  • No traps = no trap losses

  • No transformers = no power bottlenecks

  • Resonant stubs ensure clean, efficient multiband operation

  • DBFC system provides a true 40m counterpoise without long wire radials

  • Optimised for low SWR and wide usable bandwidth

Radiation pattern simulations are performed using FEKO, the same electromagnetic modelling suite used in aerospace and defence applications.


What’s Included

  • MV7 antenna system

  • Stainless steel mounting hardware

  • FAIR‑RITE FT240‑43 toroid

  • Full assembly manual

  • Serial‑numbered quality documentation


Ideal For

  • HF DXers

  • Operators with limited space who still want 40m performance

  • High‑power stations

  • Installations requiring long‑term mechanical reliability

  • Anyone wanting a premium, trap‑free multiband vertical.


Technical Details on Operation

The MV7 is developed from the proven MV6 platform and shares much of its mechanical structure. Its key advancement is the redesigned central radiating element, now a true dual‑band system for 40m and 20m. This is achieved by adding a precision‑wound loading coil topped with a capacitive hat. The combination isolates the lower portion of the 20m band while simultaneously providing the correct inductive loading required for efficient 40m operation.

Above this dual‑band section, the remaining radiator—approximately 2.2 metres in length—is formed from two lightweight telescopic aluminium tubes. These sections are engineered for low wind resistance, easy adjustment, and precise calibration across the entire 40m band.

A major innovation introduced in the MV7 is its redesigned ground‑plane system. Instead of the MV6 layout, the MV7 employs Grazioli’s DBFC (Dual Band Folded Counterpoise)system, a patent‑pending design that creates a compact and highly efficient dual‑band counterweight.

The DBFC system uses a 1mm AISI316 stainless‑steel 19‑strand cable, anchored to the tip of one of the four radials. The dramatic difference in diameter between the 10mm aluminium radial and the 1mm cable creates a high‑impedance junction. This allows only the 40m current to flow into the cable, while higher bands such as 20m and above continue to operate normally on the aluminium radial structure.

The combined length of the stainless‑steel cable and its aluminium radial forms an electrically correct ¼‑wave counterpoise for 40m. This counterweight is then folded back toward the adjacent radials, reducing the antenna's physical footprint and eliminating the need for long wire radials or lossy-loadedradial systems.
