Overview

What it is and who it is for

The Txpro TXKRA4A is a 6 inch (153 mm) VHF helical antenna for portable radios, covering 136 to 174 MHz. It is an omnidirectional, vertically polarized antenna with 50 ohm impedance, a 50 watt maximum input power and a monopole (flat or thread) termination.

It is listed as an alternative to the Kenwood KRA-4A and the Motorola NAD6502 and HAD9338, and as compatible with Kenwood TK-240, TK-270, TK-280, TK-290, TK-2100, TK-2200 and TK-2300 and Motorola GP300, GP350, GP68, P110, SP10, SP50, PRO5150, HT750 and EP450 radios.
