Komunica X-50-PWR VHF/UHF 144-430MHz 350W High Power Base Antenna

The Komunica X-50-PWR stands out as a reference for fixed stations seeking an ideal compromise between reduced size and high performance. This omnidirectional vertical antenna is specially designed to cover the 144 MHz and 430 MHz bands with a yield superior to classic quarter-wave antennas. It is aimed at both amateur radio operators wishing to boost their local station and professional installations requiring robustness at all times.

Key Features

• Exceptional power: Unlike standard versions, this PWR model supports up to 350W, ideal for the use of amplifiers.
• High gain: With 7.2 dBi in UHF, it offers excellent penetration in urban environments and extended range in open areas.
• Premium Construction: The fiberglass tube protects the radiating elements from corrosion and weather variations.
• SWR Stability: Factory preset to offer a very low standing wave ratio across all amateur bands.
• Easy installation: Its length of 1.7m allows easy installation on a roof, a balcony or a pylon without excessive wind load.
