GPS Active Antenna 1575.42 MHz

This GPS active antenna operates at a centre frequency of 1575.42 MHz with a bandwidth of CF±5 MHz. It uses right-hand circular polarization and delivers 2 dBic gain at zenith. The unit is built for vehicle roof or top-box mounting to improve satellite reception.

Screw Mount MCX Connector RG174 Cable

The antenna features a screw mounting method and an MCX connector for direct attachment to compatible GPS receivers. A RG174 cable links the antenna element to the connector. Installation requires a receiver with an MCX antenna input and a suitable mounting surface for the screw base.

IP65 IP67 Rated -40°C to +85°C

The radome carries an IP65 to IP67 ingress rating excluding the cable outlet and withstands operating temperatures from -40°C to +85°C. It meets vibration specs of 10 to 55 Hz with 1.5 mm amplitude for two hours. Buyers needing magnetic mounting or a different connector type should look elsewhere.

Questions about this item

What is the maximum operating temperature before the antenna reaches its thermal limit?

The antenna is rated for continuous operation up to +85 °C, so sustained use in hotter environments would exceed its specified thermal limit.

How much power does the active antenna draw when running all day?

The built-in LNA provides 28±2 dB gain with a typical noise figure, drawing only a few milliamps from the GPS receiver's 3–5 V supply.

Which connector must the GPS receiver already have for this antenna to plug in directly?

The antenna terminates in an MCX male connector, so the receiver needs a matching MCX female port for a direct connection.
