Enhanced for Heavy Duty Usage and Durability
At Chameleon Antenna, we understand the importance of reliable and durable equipment. That's why all the wires provided with our systems have been specifically enhanced for heavy-duty usage. We have two versions available to suit different requirements.
Militarized Wire
On the left side, we offer the militarized wire, designed to meet the demands of military operations. This wire features a braided Tinned Copper KEVLAR PTFE (Teflon) (-70°C to 150°C) wire mesh that is woven around a KEVLAR core. This robust construction ensures excellent durability and performance in even the most challenging environments.
Civilian Wire Version
On the right side, we have the civilian wire version. This wire utilizes KEVLAR fiber parallel to the stranded Tinned Copper wire. While not as rugged as the militarized wire, the civilian wire still provides reliable performance and durability for civilian applications.
Field Evaluation of the CHA TACYAGI-70 by U.S. Marine Corps Personnel
After extreme pressure I am please to finally share the AAR from MECS-38:
The Chameleon Antenna CHA TACYAGI-70 Tactical Foldable Yagi was employed during Steel Knight in support of UHF line-of-sight communications at the Air Combat Element Network Operations Center (NOC). The antenna was evaluated as a directional alternative to fielded program-of-record (PoR) omnidirectional antennas on the 117G and 163 to improve link reliability, extend LOS range, and reduce unintended electromagnetic signature within a congested operating environment.
During operations, the TACYAGI-70 was used to deliberately extend UHF LOS between distributed ACE nodes in East Miramar and CPEN with adjacent elements operating at the edge of coverage. Compared to PoR omnidirectional antennas, the directional Yagi consistently delivered improved signal strength and link stability. Operators observed clearer audio, fewer retransmissions, and sustained connectivity at ranges where omnidirectional antennas produced intermittent or marginal comms. The focused gain allowed energy to be pushed where it was needed rather than wasted in non-mission-essential directions.
Electromagnetic spectrum observations were conducted using a spectrum analyzer during transmission events. When compared directly against omnidirectional antennas, the TACYAGI-70 exhibited reduced off-axis emissions and lower observable EMS spikes outside the primary lobe. While emissions were still detectable—as expected—the overall RF footprint was tighter and more controlled. This indicated more efficient energy concentration and reduced RF spillover into adjacent sectors, supporting better EMS discipline within the ACE environment.
Mounting and repositioning were straightforward and supported rapid optimization of antenna height and orientation without disrupting operations. Directional alignment required deliberate operator awareness, but the tradeoff was acceptable given the performance gains.
Bottom Line Up Front (BLUF): "I would buy this antenna for the squadron. Its price point is unbeatable and we don't organically possess any directional antennas."
West Point Academy Chooses the CHA TACYAGI-70 for Cadet Training
At Chameleon Antenna, we take pride in supporting those who lead, protect, and innovate. That’s why we’re excited to share that West Point Academy — the United States Military Academy — has integrated our CHA TACYAGI-70 antennas into their cadet radio training program.
West Point instructors recently ordered ten CHA TACYAGI-70 units for a specialized training exercise. The mission? To teach cadets the principles of directional antenna operation by locating a beacon set one mile away. Using tools like SDR++ for signal strength analysis and FLDIGI for signal decoding, cadets practiced tracking and interpreting RF signals — a critical skill in modern communications and field operations.
The feedback?“
"These Cha Yagis are absolutely fantastic and have helped me make this an exceptionally effective lesson.”
For Chameleon Antenna, this partnership is more than a sale — it’s a testament to the rugged design, reliability, and performance of the CHA TACYAGI-70. Seeing our equipment in the hands of the next generation of military leaders at West Point underscores our commitment to delivering mission-ready solutions for both field operators and training environments.
The CHA TACYAGI-70: Built for Field Use, Trusted by Professionals
Designed for tactical, portable, and emergency communication, the CHA TACYAGI-70 is a foldable Yagi antenna optimized for quick deployment and precise direction finding. Its compact form factor, field durability, and compatibility with Chameleon’s full ecosystem of mounts make it a trusted choice for military, first responders, and EMCOMM operators worldwide.
We’re honored to support West Point’s mission — and proud to know the CHA TACYAGI-70 is playing a role in shaping future leaders.
