Gizmotchy G45

The Gizmotchy G45 is a high-performance, dual-polarity 4-element beam antenna designed for the 10-meter (Amateur) and 11-meter (CB) radio bands. Known for its unique 3-leg design per element, it allows for simultaneous horizontal and vertical polarization using two separate feed lines.
Key Specifications (G45 Model)
Power Handling: Rated for up to 5,000 Watts peak power (the “5” in G45 typically denotes the 5kW power capacity compared to the 1.5kW G41).
Gain: Offers approximately 15 dB of forward gain with a 40x power multiplication factor.
Dimensions: Features a 12.75 ft boom with a turning radius of approximately 11 feet.
Construction: Built with seamless aircraft-grade aluminum and weighs roughly 18 lbs.
Front-to-Back Separation: 28 dB, providing strong directional signal rejection.
Features and Customization
Dual Polarity: Uses two gamma matches to allow switching between vertical and horizontal modes, which is useful for reducing interference or matching the polarity of another station.
Expandable Design: Gizmotchy antennas are modular; a G45 can be upgraded to 5 or more elements later by adding Power Booster kits and extension booms.
Wind Survival: Rated for up to 90 MPH, though support kits are recommended for larger configurations (5+ elements).
