The Diamond W719 is a dual-band wire dipole antenna engineered for fixed base station installations operating across the 160-meter (1.9MHz) and 40-meter (7MHz) HF amateur radio bands. This specialized antenna architecture allows operators to deploy a 160-meter band station within restricted spatial constraints, consolidating two distinct operating bands into a single antenna layout. Built with a low-weight design relative to its size, the entire wire assembly measures approximately 30 meters in total length and has a net weight of approximately 2 kg.
For high-power operational compliance, the W719 features a maximum power handling capability of 1.2kW PEP (Peak Envelope Power), providing robust headroom for professional trade stations and amateur radio transceivers. The electrical network matches standard 50-ohm transmission lines, maintaining a Voltage Standing Wave Ratio (VSWR) of less than 1.5:1 when measured at the resonance frequency point. The central balun matching block terminates in a standard UHF female (SO-239 profile) RF interface connector.
