CHA MPAS READY Product Guide

Overview

The CHA MPAS READY Product Guide by Chameleon Antenna™ is the definitive technical and visual reference for the Modular Portable Antenna System (MPAS) family — a line of field-proven, modular HF antenna components engineered for adaptability, durability, and mission flexibility.

Developed in Nevada, USA, this guide demonstrates how operators can build, customize, and optimize their MPAS configurations to meet a wide range of field conditions, propagation environments, and communication objectives.

Chameleon Antenna’s MPAS READY ecosystem is recognized for being versatile, dependable, stealth, and built to last, providing seamless modularity across amateur, emergency, and tactical radio operations.

Purpose and Design Philosophy

The guide introduces users to Chameleon’s “building block approach” — empowering operators to mix and match components like coils, transformers, whips, mounts, and counterpoises.

This modularity allows users to:

• Adapt to varying band conditions and mission profiles.
• Incrementally upgrade systems without obsolescence.
• Transition between portable, base, and stealth installations.

By following the illustrated Tech Tree at the beginning of each section, users can build their ideal configuration in four steps:

1. Select a mount.
2. Select a base (MCC, BV, or Hybrid Transformer).
3. Select a radiator (whip or wire).
4. Select a counterpoise.

Adapters can then be added for mounting, coaxial, or custom mechanical compatibility.

Key Product Sections

1. MCC-Based Configurations

These configurations use the Multi-Configuration Coil (MCC) for base loading and variable tuning.

Models include:

• CHA PRV (Standard) – MCC + SS58 + 4 × 12.5 ft counterpoise; portable, compact, and tuner-free.
• CHA PRV (Wheel Winder) – Single 34 ft counterpoise for rapid deployment.
• CHA PRV (MIL) – Uses the longer 9’4” MIL WHIP for enhanced 60–15 m performance.
• CHA PRV (SS17) – Employs the 17 ft telescopic SS17 whip for 60–10 m coverage.

Each is presented with full performance charts and attribute ratings for efficiency, portability, stealth, and EMCOMM suitability.

2. BV-Based Configurations

These use the Blank Adapter Base (BV) to build resonant single-band quarter-wave verticals:

• CHA BV (SS17) – 20–6 m coverage, simple and efficient.
• CHA BV (SS17 + 40M Coil) – 40 & 30 m resonant operation.
• CHA BV (SS25) – Extended-length 25” whip, 30–6 m.
• CHA BV (SS25 + M25 Coil) – 40 m optimized loaded vertical.
• CHA BV (LZ Sloper) – Wire-based variant for 80–30 m and NVIS EMCOMM use.

These systems emphasize simplicity, portability, and high field reliability.

3. Hybrid Mini / Micro-Based Configurations

Broadband configurations using Hybrid Mini or Hybrid Micro transformers for unmatched frequency agility.

Highlighted systems include:

• CHA MPAS Lite – Compact broadband vertical covering 160–6 m with SS17 or SS25 whips and optional counterpoise kits.
• CHA MPAS 2.0 – Full man-packable system with MIL WHIP, MIL EXT, and 60 ft antenna wire variants for NVIS or DX.
• CHA MPAS Lite (LZ Sloper) – Inverted Lazy Sloper setup for long-distance or NVIS communication.
• CHA TDL (Tactical Delta Loop) – Dual-whip broadband loop for 80–6 m with excellent low-noise performance.

Each configuration includes detailed attribute charts, frequency coverage, and pro tips for field optimization (e.g., use of Capacity Hat or Guy System).

4. Custom, Antenna, and Coaxial Adapters

The guide also catalogs all MPAS Ready accessories to ensure complete interoperability:

Custom Adapters

• CHA Blank Adapter – Electrical & mechanical base for 3/8-24 whips or coils.
• CHA SS Insulator – Electrically isolates sections to reduce loss.
• CHA SURVEYOR-A – Converts 5/8-11 tripod threads for stable antenna mounting.
• CHA TRIPOD ADAPTER – Adapts 1/4-20 camera tripods for 3/8-24 antennas.
• CHA MAS-T-A – Universal 1” mast adapter with wire/guy line anchors.
• CHA PUCK HUB – Connects up to six counterpoise wires simultaneously.
• CHA SS ADAPTER / SHACKLE KEY RING – Converts thread sizes or attaches wire terminations.

Antenna Adapters

• Quick Release / Quick Release HD – Rapid 3/8-24 component connection for field speed and reliability.

Coaxial Adapters

• BNC-UHF series, PL-259 Quick Release, Right-Angle, and SO-239-PCAP protectors — all precision-machined for durability and ease of field use.

Product Attributes Explained

The guide includes a universal attribute chart helping users evaluate performance across:

• Band coverage (160–6 m visual chart)
• Power handling (SSB, CW, Digital modes)
• Efficiency (low, mid, and high bands)
• Portability, Stealth, EMCOMM suitability, and Setup time

The analogy is clear: just as a Formula 1 car isn’t ideal off-road, every antenna involves trade-offs. These charts help users choose the configuration that best aligns with their operational environment and mission needs .

Applications

The CHA MPAS READY ecosystem is optimized for:

• Amateur radio (POTA, SOTA, Field Day)
• Emergency communications (EMCOMM, NVIS)
• Military and tactical field deployments
• Stealth and HOA-restricted operations
• Expeditionary and off-grid setups

SPECS:

• 44 pages
• 8.5" X 5.5"
• Color

Conclusion

The CHA MPAS READY Product Guide is more than a catalog — it’s a modular antenna engineering handbook that teaches users how to design, deploy, and master Chameleon’s highly adaptive systems.

Whether for emergency preparedness, tactical operations, or portable ham radio adventures, this guide equips users to assemble the right antenna for any mission.
