The premium DIAMOND VX4000 – Triband base antenna Frequency: 144/430/1200 MHz Length: 1.3m Weight: 0.7kg Connector: N Type: 1/2 (144MHz) 2 x 5/8 (430MHz) 5 x 5/8 (1200MHz) without radials. is a commercial-grade, ultra-compact fixed station radiator precision-engineered to deliver secure voice synchronization, simultaneous multi-band spectrum tracking, and elite antenna line conditioning across active communication grids. Manufactured by Diamond Antenna to satisfy rigorous professional standards, this high-performance base station tower overhauls legacy single-band vertical arrays or cumbersome ground-plane setups that suffer from wind-loading vulnerabilities and real estate space restrictions. It stands as an essential operational procurement asset for industrial utility bases, municipal tracking facilities, backup communications network infrastructure nodes, and high-volume B2B radiocommunication hardware wholesale distribution networks looking to source authentic, original factory-genuine active components.
The advanced internal RF core of this high-compliance infrastructure node features broad frequency agility optimized for simultaneous resonance across an elite tri-band allocation spectrum, charting a target frequency: 144/430/1200 MHz (VHF, UHF, and SHF 23cm bands) passband grid. The specialized internal element structure configures the radiator as a high-efficiency type: 1/2 (144MHz) wave element on VHF, moving into a stacked colinear 2 x 5/8 (430MHz) wave assembly on UHF, and finalizing into a high-density 5 x 5/8 (1200MHz) wave phasing matrix on the microwave band. This advanced multi-stage internal architecture focuses radiation lobes tightly toward the horizon, capturing deep fringe-area signals while generating balanced omnidirectional tracking coverage without requiring the installation of physical metal counterpoise wires.
Constructed to thrive through punishing environmental deployment schedules and multi-season weather stress, the VX4000 features a highly specialized completely without radials design scheme, presenting an ultra-low mechanical wind-drag profile. Housed inside a heavy-duty, weather-tight fiberglass radome shell that seals out ambient moisture lines, the array measures a compact physical length: 1.3m and registers a lightweight net structural weight: 0.7kg, ensuring minimal vertical torque on roof masts or side-mount bracket kits. The feedpoint terminates in a premium low-loss high-retention connector: N female chassis port engineered to secure maximum impedance stability, providing a turnkey system built to protect delicate transmitter final amplifiers from unexpected impedance mismatch breakdown failures.
