430-450MHz 4dBi Gain TNC male antenna whip antenna

Product introduction

1. Wide UHF Frequency Coverage

Covers 430–470MHz with 20MHz bandwidth, supporting multiple UHF channels for flexible communication systems.

2. 4dBi Gain for Extended Range

Provides 4dBi of gain, significantly improving signal strength and transmission distance compared to basic 0dBi or 2dBi antennas.

3. Low VSWR (≤2) for High Efficiency

Voltage Standing Wave Ratio ≤2 ensures minimal signal reflection, maximizing power transfer and reducing interference.

4. Rugged TNC Male Connector

Equipped with a durable TNC male connector – threaded for vibration-resistant connection, ideal for mobile and industrial terminals.

5. Compact Whip Design

Lightweight (50g) and only 308mm in length, easy to integrate into portable or fixed terminal devices without adding bulk.

Application scenarios

Wireless data transceivers – Used in SCADA, RTU, or telemetry units operating in 430–470MHz band.

Industrial remote control – Provides stable signal for crane, gate, or machinery remote controllers.

Amateur radio (UHF band) – Suitable for ham radio operators needing a compact 70cm band antenna.

IoT gateway devices – Connects to terminal nodes in agricultural or environmental monitoring systems.

FAQ

Q: What frequency range does the GL450TNC antenna support?

A: It supports 430–470MHz (UHF band) with a 20MHz typical bandwidth.

Q: What type of connector does this antenna have?

A: It comes with a TNC male connector – threaded and weather-resistant for secure attachment.

Q: Is this antenna suitable for outdoor use?

A: It can be used outdoors, but the datasheet does not specify an IP rating. For permanent outdoor installation, we recommend additional weather protection.

Q: What does 4dBi gain mean in practice?

A: 4dBi gain means the antenna focuses radio energy horizontally, providing about 2.5x more effective range than a 0dBi isotropic antenna under same conditions.

Q: What is the maximum input power?

A: The maximum power handling is 30W (continuous).

Q: Is the polarization vertical only?

A: Yes, it is vertically polarized – ideal for most land-mobile and base station communications.
