The Diamond X300A is a dual-band, high-performance base station antenna designed for 2m (VHF) and 70cm (UHF) amateur radio bands. It is engineered to provide reliable communication with a focus on durability, weather resistance, and ease of installation.
The primary function of the X300A is to transmit and receive radio signals on the 144-148 MHz (2m) and 435-450 MHz (70cm) frequency bands. It utilizes a high-performance C-Load structure with Liner Phase Shifter technology, which contributes to its high power rating, low VSWR (Voltage Standing Wave Ratio), and broad band coverage. This design ensures efficient signal transfer and reception across both operating bands. The antenna features a DC ground structure, which is a crucial safety feature. This design helps to protect connected radio equipment from high voltage surges caused by lightning strikes, diverting the electrical energy safely to ground. This makes the antenna suitable for long-term outdoor installation where lightning exposure is a concern.
