Product Introduction
Ultra-Wideband Professional Coverage:Achieves breakthrough ultra-wideband coverage in the 134-174MHz VHF and 400-520MHz UHF bands, perfectly compatible with various professional communication standards, providing a one-stop antenna solution for different types of wireless equipment.
Intelligent Gain Optimization Design:Employs band-adaptive gain technology, providing 2.15dBi gain in the VHF band and boosting to 3.2dBi gain in the UHF band. Precise optimization is performed for the propagation characteristics of different frequency bands, ensuring maximum performance in each band.
Dual-Interface Universal Compatibility: Innovatively integrates both BNC and SMA industry standard interfaces, allowing direct connection to most professional wireless equipment without adapters, greatly improving the applicability and deployment flexibility of the equipment.
Precision Structural Engineering Design:A scientifically calculated ideal length of 470mm, combined with a lightweight design of only 75 grams, using aerospace-grade aluminum and special plastic composite structures, achieving excellent portability and durability while ensuring electrical performance.
Intelligent Gain Optimization Design: Superior Transmission Performance
Through a sophisticated multi-band matching network design, it maintains an excellent VSWR of <1.5 across the wide 186MHz VHF band and 120MHz UHF band, ensuring efficient power transmission across the entire frequency range.
Application Scenarios
