VHF/UHF Base Antenna X-300H, one of the most popular and reliable VHF/UHF base antennas worldwide, is designed for radio amateurs and professionals who demand high performance and long-lasting durability.
Manufactured by Diamond Antenna, known for the quality and consistency of its products. The antenna is dual-band (2m / 70cm) and offers excellent gain at 144 MHz and 430 MHz, with a flat radiation pattern for reliable coverage in local and extended communications.
It uses multiple stacked radiators, enhancing performance without compromising signal stability. Its construction is designed for continuous outdoor use:

The grounded radiator effectively protects against static discharges and electrical noise, a feature that distinguishes Diamond antennas from cheap imitations. The X-300 withstands harsh weather conditions and high wind speeds, while it is delivered with a complete mounting set (clamps, U-bolts, stainless steel spokes) for easy and secure installation on a mast or rooftop. The SO-239 connector is protected from external factors, increasing the antenna's lifespan.
Ideal for:
- Fixed VHF/UHF stations
