Great Radios Deserve Great Antennas
From civilian applications to military ready tactical antennas, Chameleon Antenna has you covered.
The CHA URT1 MB (Mounting Bracket) is finally here!
Introducing the new CHA URT1 MB (Mounting Bracket) for the CHA URT1 Universal Remote Tuner.
At first glance, it may look like a simple mounting bracket.
It isn’t.
The CHA URT1 MB fundamentally changes what operators can do with the URT1 by allowing the remote tuner to be mounted on virtually any 3/8-24 antenna mounting system, including the CHA Spike Mount, CHA Universal Clamp Mount (UCM), CHA Surveyor-A, CHA Jaw Mount, CHA Carbon Fiber Mini Tripod, CHA PORTA MAST, CHA CFM34HD Carbon Fiber Mast, and countless third-party mounting solutions.
The real advantage is what happens when you combine the CHA URT1 MB with an SS17 or SS25 telescopic whip and elevate the entire antenna system above ground.
Most vertical antennas suffer from one unavoidable problem: ground losses.
When a vertical antenna is operated near the ground, valuable RF energy is absorbed by the earth. Every watt lost into the ground is a watt that never makes it to the ionosphere.
With the CHA URT1 MB, operators can now elevate the radiator and counterpoise system using a CHA PORTA MAST or a properly guyed CHA CFM34HD. By elevating the antenna system and radials above the ground, RF losses are reduced and antenna efficiency is increased.
The result is a stronger transmitted signal, improved receive performance, and more effective low-angle radiation for long-distance DX communications.
But there is another major benefit that many operators overlook.
Noise.
In urban and suburban environments, most man-made noise originates close to ground level. LED lighting, solar systems, battery chargers, switching power supplies, networking equipment, appliances, and countless consumer electronics create a layer of RF noise that surrounds our homes and neighborhoods.
By elevating the antenna system above many of these noise sources, operators often experience a significant reduction in noise floor. A quieter antenna allows weaker signals to emerge from the background, improving signal-to-noise ratio and making DX stations easier to copy.
Many operators discover that reducing noise produces a larger improvement in real-world performance than increasing transmitter power.
The combination of a CHA URT1, CHA URT1 MB, SS17 or SS25, and an elevated radial system creates a highly effective portable HF antenna capable of delivering outstanding performance from HOA properties, urban environments, RV parks, campgrounds, field operations, emergency communications deployments, and DX expeditions.
Whether your goal is chasing DX, operating POTA, supporting EMCOMM activities, or simply improving your station’s performance in a noisy urban environment, the CHA URT1 MB provides a new level of flexibility and capability for the CHA URT1 platform.
CHA CFM-34 is BACK in STOCK
Unlike ordinary carbon fiber masts, CHA CFM-16 and CHA CFM-34 are manufactured entirely from premium 3K Twill Carbon Fiber. This advanced woven construction provides superior durability, improved resistance to splitting and cracking, and better load distribution throughout the mast sections.
CHA MCC 2.0
Multi-Configuration Coil 2.0
The Heart of the Portable Resonant Vertical System
The CHA MCC 2.0 (Multi-Configuration Coil 2.0) is a high-performance, field-adjustable loading coil engineered for operators who demand maximum flexibility from a compact portable antenna system. Originally developed as the core component of the popular CHA PRV 2.0, the MCC 2.0 is now available individually for amateur radio operators, emergency communicators, military users, and antenna experimenters who want to build their own custom resonant vertical antenna systems.
INTRODUCING THE CHA CFM-34 HD
Heavy-Duty Portable Carbon Fiber Mast
The CHA CFM-34 HD is a premium heavy-duty portable carbon fiber mast engineered for serious amateur radio operators, EMCOMM teams, military communicators, preppers, POTA/SOTA enthusiasts, and HOA-conscious operators who demand maximum portability, strength, and versatility in the field.
INTRODUCING THE CHA LEFS FEATHER EFHW
The CHA LEFS FEATHER (Lightweight End Fed Sloper) is a purpose-built portable HF antenna designed for operators who demand maximum performance with minimum weight.
Weighing only 3.4 oz (96 grams), this antenna is engineered for POTA, SOTA, backpacking, emergency communications, and rapid deployment where portability and reliability are critical.

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.
