Overview

The TOXU TX-A115 is a stainless steel whip antenna designed for compatible VHF mobile radio equipment operating within 136–174MHz.

The antenna provides 3.0dBi nominal gain and supports maximum input power of 200W. Its approximately 0.5m stainless steel whip provides a flexible external antenna structure for vehicle-mounted communication applications.

A spring base is integrated between the whip and connector section. This structure allows the antenna to accommodate movement and vibration during vehicle operation.

The standard TX-A115 configuration uses an HF/SL16-J/M type connector for connection to a compatible antenna mount or vehicle radio system. The exact mating interface should be confirmed before ordering.

Typical applications include VHF mobile radios, vehicle-mounted two-way radios, fleet communication equipment, taxi radio systems, amateur radio equipment, and compatible emergency communication systems.

Key Features

136–174MHz VHF Frequency Range

The TX-A115 is designed for compatible VHF mobile radio and two-way communication equipment operating within 136–174MHz.

3.0dBi Nominal Gain

The specified antenna configuration provides 3.0dBi nominal gain within the stated VHF operating range.

Stainless Steel Whip

The approximately 0.5m radiating element is manufactured from stainless steel, providing a flexible whip structure for external vehicle installation.

Spring Base Design

The integrated spring base allows the antenna whip to flex when subjected to vehicle movement, vibration, or light mechanical contact.

200W Maximum Input Power

The TX-A115 supports maximum input power of 200W under the specified product configuration.

HF/SL16-J/M Type Connector

The antenna uses an HF/SL16-J/M type connector for installation with a compatible mobile radio antenna base or vehicle mounting system.

Vehicle-Mounted Communication Application

The antenna structure is suitable for compatible VHF radio systems installed on taxis, fleet vehicles, logistics vehicles, service vehicles, and other mobile communication platforms.

Technical Specifications

The listed specifications are based on the currently available TX-A115 product information. The connector and mating antenna mount should be confirmed before ordering.

Applications

• VHF Mobile Radios

• Vehicle-Mounted Two-Way Radios

• Amateur Radio Equipment

• Taxi Communication Systems

• Fleet Communication Equipment

• Logistics Vehicle Radios

• Service Vehicle Communication Systems

• Compatible Emergency Communication Equipment

• Vehicle-Mounted VHF Repeaters

The connected radio equipment must operate within 136–174MHz and use a compatible antenna interface.

System Integration

Before ordering, confirm that the mobile radio or communication equipment operates within the TX-A115 frequency range of 136–174MHz.

The standard antenna uses an HF/SL16-J/M type connector. The connector type and mating vehicle antenna mount should be checked before product confirmation.

The antenna should be installed vertically on a suitable vehicle antenna base. The mounting position should remain clear of nearby metal obstructions that could affect antenna performance.

The spring section should be allowed sufficient movement and should not be restricted by the vehicle body or surrounding equipment.

The antenna connector and mounting base should be securely fastened before operation.
