Gizmotchy G651

The Gizmotchy G651 is a high-performance 6-meter (50 MHz) beam antenna designed for amateur radio base stations. It features a unique dual-polarity design that allows for simultaneous or switchable horizontal and vertical polarization.
Key Specifications
Design: 5-element beam with 15 sets of elements (typically configured as 5 horizontal and 5 vertical elements).
Frequency Range: 6 Meter band (50–54 MHz).
Power Handling: Rated for up to 1,500 Watts PEP.
Gain: Offers approximately 12–14 dB of forward gain.
Physical Dimensions:
Boom Length: 12 feet.
Boom Outer Diameter: 1.25 inches.
Turn Radius: 8 feet.
Feeding: Twin feed system using separate horizontal and vertical gamma matches (50 ohms).
Construction & Expandability
The antenna is built using aircraft-grade 6063-T5 aluminum for the boom and even tougher 6006 alloy for the elements to ensure durability. A hallmark of the Gizmotchy line is its modularity; the G651 can be further expanded by adding a Gizmotchy Power Booster (GPB6), which adds more director elements to increase gain.
