TACYAGI-70 · VHF/UHF & Yagi
A VHF/UHF radiator, directional antenna, or related component.
Why operators make room for it
Build a portable VHF/UHF position with purpose
Portable VHF/UHF work becomes far more intentional when the operator can control where the signal goes and how the antenna is polarized.
This level of compatibility means that no matter the situation—whether in the field, on a rooftop, or mounted on a vehicle—users can rapidly deploy and stabilize the CHA TACYAGI-70 .
For the operator, that means a station that can be aimed and verified for the intended path, with assembly order, polarity, support, and clearance treated as part of performance.
