Product Description

The A1211 AC Series is suited to mobile installations that favor a flexible radiator over a heavier rigid whip. Its documented frequency choices cover multiple LMR bands, 220 MHz, and selected ISM use while keeping each ordered antenna tuned to its chosen range.

A 24-inch maximum stainless-steel radiator, triple-plated brass nut, and machined contact form a straightforward standard-duty NMO configuration. Chrome/brite and black versions are available for the same frequency-selection structure.

Ideal applications: standard-duty mobile LMR, 220 MHz, and supported ISM installations requiring a flexible whip.

Example Model Configurations: A1211A, A1211A-152-MAL-06, A1211A-152-MZL-06, A1211AC, A1211B, A1211BC
