URT1 MB · Tuners & Matching
A tuning, matching, analysis, or remote-control device for a documented RF system.
Why operators make room for it
Measure first, tune deliberately, then put the signal on the air
Field efficiency improves when tuning and analysis become a quick verification step instead of a troubleshooting event after everything is raised.
Introducing the new CHA URT1 MB (Mounting Bracket) — a rugged, versatile, and highly adaptable mounting solution designed specifically for the CHA URT1 Universal Remote Tuner . Engineered around the proven MPAS READY ecosystem, the CHA URT1 MB transforms the URT1 into a compact, remotely tuned multiband HF antenna platform for portable, mobile, tactical, HOA, RV, and emergency communications operations.
For the operator, the value is confidence: a measurable, repeatable path from antenna assembly to a verified match within the device and system limits.

CHA URT1 MB
Universal Remote Tuner Mounting Bracket
Introducing the new CHA URT1 MB (Mounting Bracket) — a rugged, versatile, and highly adaptable mounting solution designed specifically for the CHA URT1 Universal Remote Tuner. Engineered around the proven MPAS READY ecosystem, the CHA URT1 MB transforms the URT1 into a compact, remotely tuned multiband HF antenna platform for portable, mobile, tactical, HOA, RV, and emergency communications operations.
The CHA URT1 MB enables operators to securely mount the outdoor URT1 Tuner Unit directly onto virtually any mounting platform equipped with a 3/8-24 mounting system, making it fully compatible with the growing family of MPAS READY mounts and accessories including:
- CHA Spike Mount
- CHA Universal Clamp Mount (UCM)
- CHA Surveyor-A
- CHA Carbon Fiber Mini Tripod
- CHA Jaw Mount
- Camera tripods with the CHA Tripod Adapter
- Any third-party 3/8-24 compatible mount system
This universal compatibility makes the CHA URT1 MB one of the most flexible remote tuner mounting systems available today.
Designed for rapid deployment and field efficiency, the CHA URT1 MB allows the URT1 remote tuner to be mounted directly at the antenna feedpoint where tuning performance is optimized and feedline losses caused by high SWR are minimized. The CHA URT1 itself is capable of matching antennas from 5 to 1500 Ohms, covering 1.8 MHz to 54 MHz, with 16,000 memory locations for lightning-fast tuning recall.
The CHA URT1 MB works exceptionally well with:
- CHA SS17 Telescopic Whip
- CHA SS25 Telescopic Whip
- MIL WHIP systems
- Random wire antennas
- Hybrid coaxial-fed systems
- Portable vertical configurations
The mounting bracket supports both:
- Direct-fed vertical antenna configurations using the URT1 Beehive Connector
- Hybrid coaxial-fed configurations for broadband or transformer-fed systems
Using the CHA SS17 or CHA SS25 with the URT1 MB creates an extremely efficient and easy-to-deploy remotely tuned HF vertical antenna covering 80M through 6M, ideal for:
- HOA operators
- POTA / SOTA activations
- EMCOMM
- RV camping
- Field day operations
- Military and tactical communications
- Rapid deployment portable HF operations
Because the CHA URT1 MB follows the MPAS READY modular philosophy, operators can easily integrate it into existing antenna systems and customize configurations based on mission requirements, operating environment, or propagation conditions. The MPAS READY system was specifically developed to provide “building block” flexibility for antenna operators seeking maximum versatility and portability.
