The Diamond X300N dual-band base station antenna is a commercial-grade, high-performance omnidirectional vertical mast engineered for fixed station deployments requiring maximum signal range and extreme environmental resilience. Measuring 3.10 meters in total length and constructed in two high-integrity fiberglass sections with a secure joint system, this premium antenna balances exceptional mechanical stability with elite electrical performance. Weighing only 1.5 kg, its low-drag structural shroud is built to withstand rigorous wind loads up to a velocity threshold of 50 m/sec, making it a premier infrastructure procurement asset for regional utility monitoring, commercial dispatch hubs, emergency backup communication centers, and high-volume B2B radiocommunication distribution networks across European markets.
The advanced internal phasing network of the Diamond X300N is factory-pre-tuned to deliver high-aperture radiation patterns across the primary VHF and UHF bands. On the 144 MHz spectrum, it operates as a 2 x 5/8 wave C-Load configuration yielding a powerful 6.5 dB gain metric, while shifting into a 5 x 5/8 wave C-Load configuration on the 430 MHz band to deliver a commanding 9.0 dB gain profile. It handles a continuous input RF maximum power of 200 Watts (FM) across a nominal 50-Ohm characteristic system impedance, all while maintaining a strict, equipment-protecting VSWR of less than 1.5:1. Terminated at its base assembly with a heavy-duty, low-loss N-Type Female connector and packaged with mounting hardware accommodating mast diameters from 30 mm to 62 mm, it ensures a turnkey mechanical bond for immediate system alignment and absolute fleet deployment readiness.
