The ZDA 166 MHz Directional Yagi Antenna is a rugged VHF workhorse built to pull in weak signals across the 164–170 MHz band and deliver reliable, consistent communication. Proven in the field by our MOTUS partners, this 166 MHz Yagi has become the preferred choice for demanding outdoor deployments on buildings, towers, and masts where dependable reach matters. Offered in three configurations, the lineup delivers up to 12.5 dBi of focused, directional gain with selectable horizontal or vertical polarization for system flexibility. Every unit is verified through a strict QC process to ensure a VSWR of ≤ 1.5, minimizing return loss and protecting connected radios. Each model features a 50 Ω N-Female interface, supports up to 300 W input power, and maintains a ≥ 15 dB front-to-back ratio to keep links clean in noisy environments.
