## Overview

YA0103 is the PCTEL K7153236 Gainflex UHF terminal antenna. Its shortened half-wave design is decoupled from the radio set, providing 4 dB of gain relative to a quarter-wave whip across the 440–470 MHz band.

The flexible antenna uses a highly elastic, corrosion-resistant metal shaft protected by a durable black plastic cover. Its TNC male connector uses nickel-tin-plated H59 brass with a polycarbonate insulator.
