The Diamond X50NA dual-band base station antenna is an original, precision-engineered Japanese manufacturing masterpiece designed for permanent outdoor deployment requiring exceptional omnidirectional coverage and rugged structural endurance. Measuring a balanced physical height profile of 1.7 meters and weighing an ultra-lightweight 0.9 kg, this premium antenna features a heavy-duty fiberglass radome construction capable of withstanding extreme hurricane-force environmental wind loads up to a velocity threshold of 60 m/sec. It serves as an essential, high-reliability infrastructure procurement asset for regional utility tracking, commercial dispatch command stations, amateur radio repeaters, and high-volume B2B radiocommunication distribution networks across European markets.
The advanced internal electrical phasing architecture of the Diamond X50NA is specifically optimized for high-aperture radiation performance across the designated 144–148 MHz (VHF) and 435–450 MHz (UHF) frequency ranges. On the 2-meter band, its phased layout functions as a 6/8λ wave configuration yielding a sharp 4.5 dB gain metric, while shifting into a high-density 3 x 5/8λ wave configuration on the 70-centimeter band to deliver a commanding 7.2 dB gain profile. Engineered to handle a maximum input continuous power rating of 200 Watts across a nominal 50-Ohm characteristic system impedance, it maintains a strict, hardware-protecting VSWR of less than 1.5:1. Terminated at its heavy-duty base mount with a low-loss, high-integrity N-J connector (N-Type Female) and packaged with zinc-plated u-bolt hardware accommodating mast support pipe diameters from 30 mm to 62 mm, it ensures immediate technical system alignment and absolute fleet deployment readiness.
