Start with the operator’s decision: CHA URT1-MB is the mechanical bridge that carries the CHA URT1 and provides the documented 3/8-24 radiator interface for supported vertical-whip and TDL arrangements.

How this exact system works

It is a mount, not a feed/matching unit. The URT1 remains the tuner platform; the complete antenna still needs the exact tuner, radiator, return, support, feed/control cables, isolation, and load path. Treat the product as a complete documented system: feed point, radiator, return or balanced second leg, feed line, support, geometry, power, and environment all matter.

The boundary that prevents mistakes

Its 3/8-24 thread does not make every whip or MPAS READY part compatible. Do not represent the MB as a transformer, tuner, feed point, or universal load adapter.

Use this field sequence

Install it only in a named URT1 configuration, support the assembly so the tuner and cables do not carry unintended leverage, attach the documented radiator, and verify the complete mechanical and RF path before tuning.

Source boundary

CHA URT1 User Guide 260524, URT1 Applications Guide 260612, and current product record. The exact current product, components, band, feed, support, geometry, and operating limits control; physical fit does not establish compatibility.
