Maco V 58 Ground Plane

The Maco V58 (also known as the Alpha V58) is a highly efficient 5/8 wave omni-directional base station antenna designed for CB and 10-meter amateur radio.
Key Specifications
Antenna Type: 5/8 Wave Commercial Ground Plane with 4 radials.
Frequency Range: Field tunable from 26 MHz to 33 MHz.
Power Handling: Typically rated for 1,200 to 1,500 watts (standard model).
Gain: 5 dB.
Height: Ranges from 16.5 feet to 20 feet depending on the tuned frequency.
Construction: Made from aircraft-grade aluminum.
Technical Details & Tuning
Ground Plane System: It features a dedicated ground radiator system (radials) to provide a stable reflective surface for signal transmission, enhancing signal strength and reception.
Tuning Adjustments: SWR (Standing Wave Ratio) is primarily adjusted by changing the overall length of the antenna at the top of the base section.
Mounting: The antenna can be tuned while mounted approximately 6 feet above the ground and typically retains its tuning once permanently installed at higher elevations.
Usage & Availability
Applications: Ideal for stationary base stations requiring long-distance communication (“skip”) and high-power capability.
Comparison: It is often considered an upgrade or more robust alternative to standard antennas like the Antron 99.
