Rg174 Cable Screw Antenna with SMA Male connector

Product introduction

1. Optimized for 433MHz ISM Band

Specifically tuned for 433MHz (Europe, Asia, and other regions), providing stable performance for LoRa, RF transceivers, and low‑power wide‑area networks.

2. Low VSWR (≤1.5)

Exceptional impedance matching minimizes signal reflection, ensuring maximum power transfer and protecting your RF module – ideal for battery‑powered devices.

3. Compact Screw-Type Design

Measures only 50×48mm, with a screw installation method – quick to mount on enclosures without special tools. Saves space in handheld or panel‑mounted equipment.

4. Rugged Environmental Tolerance

Operates from -40°C to +85°C, withstands up to 95% relative humidity, and passes vibration testing (10–55MHz, 1.5mm amplitude for 2 hours). Reliable for indoor and outdoor use.

5. SMA Male Connector & ROHS Compliant

Standard SMA male port ensures easy connection to modules, gateways, or development boards (e.g., Arduino LoRa shields). ROHS compliant for environmentally conscious designs.

Application Scenarios

1. LoRa IoT Sensors

Attach to temperature, humidity, or motion sensors transmitting data over 433MHz LoRaWAN networks – compact size fits inside small enclosures.

2. Remote Keyless Entry (RKE)

Integrate into car key fobs, garage door openers, or gate remote controls – screw mounting provides reliable internal antenna placement.

3. RF Modules & Development Kits

Use with 433MHz transceiver modules (e.g., RFM69, SX1278) on breadboards or custom PCBs – SMA male plugs directly into module’s antenna port.

4. Smart Home Devices

Embed into smart plugs, wireless switches, or alarm sensors for short‑range (10–100m) 433MHz control links.

5.Industrial Telemetry

Deploy in remote meter reading, tank level monitoring, or equipment status reporting where low‑cost, compact antennas are required.

Differences between similar antennas

FAQ

Q: What frequency does the GLJ058 cover exactly?

A: It is designed for 433MHz center frequency, typically covering 430–435MHz. Ideal for 433MHz ISM band applications.

Q: What is the gain of this antenna?

A: 2dBi linear gain – suitable for short to medium range (typically 50–200 meters line of sight depending on transmitter power and environment).

Q: Can I use this antenna for 868MHz or 915MHz?

A: No, it is tuned specifically for 433MHz. Using it at other frequencies will cause high VSWR and poor performance. Please see our other models for 868/915MHz.

Q: What type of connector does it have?

A: SMA male (pin inside). It mates with SMA female connectors commonly found on RF modules, LoRa shields, and spectrum analyzers.

Q: How do I install the antenna?

A: Screw the antenna onto the SMA female port of your device. For panel mounting, you may need an SMA bulkhead adapter (not included). The screw method ensures secure mechanical attachment.

Q: Is the antenna waterproof?

A: The GLJ058 is not fully waterproof, but it operates in up to 95% humidity and from -40°C to +85°C. For outdoor exposed use, we recommend adding a weatherproof enclosure or choosing a fiberglass antenna.
