Great Radios Deserve Great Antennas
From civilian applications to military ready tactical antennas, Chameleon Antenna has you covered.
The CHA PRV 2.0 is FINALLY HERE
After a long wait… we’re proud to officially reintroduce the CHA PRV 2.0.
This antenna was originally planned for release in December 2025. However, due to a massive surge in demand during the holiday season, our manufacturing capacity was fully committed to supporting our core product line. To keep up, we had to more than double production on critical components like the CHA BLANK (BNC & SO-239) and the CHA SINGLE EXT — producing well over a thousand units of each.
That level of demand forced us to delay the PRV 2.0 launch.
But now… it’s ready.
So what is the CHA PRV 2.0?
The CHA PRV 2.0 is the next evolution of our Portable Resonant Vertical antenna system, built around the new MCC 2.0 (Multi-Configuration Coil) and designed for serious portable operators.
According to the User Guide , the PRV 2.0 introduces a taller, center-loaded architecture that delivers up to 80% more efficiency compared to the original PRV, while maintaining the portability and ruggedness Chameleon Antenna is known for.
It is a true resonant antenna system, covering 40 through 6 meters without the need for an antenna tuner when properly tuned, making it ideal for field operations, POTA, SOTA, emergency communications, and HOA-restricted environments.
MPAS READY — What makes this system unique
The CHA PRV 2.0 is fully MPAS READY, and this is where Chameleon Antenna stands apart.
MPAS (Modular Portable Antenna System) is a unique ecosystem we developed so operators don’t have to start over every time they purchase a new antenna.
Instead of buying a completely separate system, you can:
- Reuse existing components
- Add or remove parts depending on your mission
- Reconfigure your antenna for different bands, environments, and operating styles
The PRV 2.0 integrates directly into this ecosystem, using components like:
- CHA SINGLE EXT (24” mast)
- CHA SS58 telescopic whip
- CHA MCC 2.0
- CHA BLANK feedpoint system
- All MPAS-compatible mounts and accessories
This means your investment grows with you. One system can become many.
Multiple Configurations — One System
The PRV 2.0 can be configured based on your needs:
- Base-loaded for compact, stealth setups (ideal for balconies, RVs, and travel)
- Center-loaded for maximum efficiency (up to 80% improvement)
- 6 meter vertical OCF dipole configuration
- Expanded configurations using other MPAS components like the SS17 or MIL WHIP
This flexibility is built into the design — not added as an afterthought.
New Feedpoint Flexibility
Operators can now easily choose their preferred feedpoint connector.
By using either the CHA BLANK BNC or the CHA BLANK SO-239 (both available now on our website), you can switch between connector types instantly without modifying the antenna system.
Built for Real Operators
The CHA PRV 2.0 was designed for:
- POTA and SOTA activations
- Field and emergency communications
- RV and mobile setups
- Apartment, condo, and HOA-restricted environments
- Operators running modern radios like the IC-705, KX2/KX3, Xiegu X6200, and more
Setup time is about 10 minutes, and the system is lightweight, rugged, and built for repeated deployment in real-world conditions.
It’s here. And it was worth the wait.
CHA PRV 2.0
Chameleon Antenna creates BAND TUNING KEYS to work with the CHA PRV2, CENTER LOADED Adjustable Coil Antenna. Let's walk through the full Review and Demonstration.
CHA TUNING KEYS (PRV/MCC)
What are the Band Keys?
According to the CHA PRV 2.0 User Guide, the Band Keys are a set of calibrated tuning strips that allow operators to quickly set the initial height of the MCC 2.0 loading coil for each band.
Instead of manually measuring coil position or relying on trial and error, you simply:
- Select the Band Key for your operating band
- Set the coil height using the key as a physical reference
- Fine-tune from there if needed
That’s it.
CHA PRV BAG
CHA PRV BAG — Built for the PRV System
When we designed the CHA PRV 2.0, we didn’t just focus on antenna performance — we also focused on how operators actually deploy, transport, and protect their gear in the field.
That’s where the CHA PRV BAG comes in.
As shown in the CHA PRV 2.0 User Guide , this bag was specifically designed to keep every component organized, protected, and ready for rapid deployment.
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.
