136-512 MHz Quarterwave Antenna

This quarterwave antenna covers a continuous 136 to 512 MHz range and is field tunable without tools. It is built for mobile radio installations that need flexible frequency adjustment on Motorola style mounts. The Makroblend polymer base provides impact resistance and weather durability for vehicle roof or trunk-lid mounting.

Tool-Free Tuning and Mount Fit

The whip adjusts by hand so installers can set the exact operating frequency on site without test equipment or cutting. A Motorola style mount is required; the antenna will not fit NMO, UHF or proprietary bases without an adapter. Verify the mount thread and ground plane dimensions before purchase to avoid fitment issues.

Questions about this item

How can I verify the antenna is transmitting properly after mounting it on a Motorola style mount?

Check SWR readings across the 136-512 MHz range and adjust the field-tunable whip length until reflected power is minimised.

What comes in the box and what extra parts are needed for installation?

The antenna ships with its Makroblend polymer base and field-tunable whip; a Motorola style mount and coaxial cable must be purchased separately.
