Trustpilot

The Diamond X‑300 is a high‑gain fixed station vertical antenna designed for the 2m and 70cm amateur bands. Built from durable fibreglass, it is pre‑tuned, fully weatherproofed, and supplied with mast mounting brackets for easy installation.

Available in both N‑type (X‑300N) and PL‑259 (X‑300PL) connector versions, the X‑300 offers flexibility to suit different station setups. With a gain of 6.5 dB (2m) and 9 dB (70cm), and a power capacity of 200W, it delivers reliable performance for base station operators.

Its 2×5/8 λ (2m) and 5×5/8 λ (70cm) design ensures efficient radiation patterns, while the antenna withstands wind velocities up to 50 m/sec. At 3.1 m length with 52 cm radials, it accommodates mast sizes from 30–62 mm and weighs just 1.5 kg, making it a robust yet lightweight solution.

Part of the Diamond Antenna X Series, the X‑300 is trusted worldwide for dependable VHF/UHF communication.
