CORONIR Vehicle Waterproof Active GPS Antenna with SMA Male Connector 28dB Gain, 3-5VDC Magnetic GPS Antenna
Quick take
The CORONIR magnetic active GPS antenna is built for vehicle or equipment installs where you want improved satellite visibility compared with an internal GPS antenna. It uses an SMA male connector, includes a 10 ft (3 m) RG174 cable, and is designed for DC power between 3V and 5V. The main compatibility catch is that your GPS receiver system must support the SMA male connection and provide the right voltage.
Pros and cons
Pros
- Waterproof, magnetic base mount for easier outdoor or vehicle installs
- Active antenna design with listed 28 dB (28 ± 3 dBic) gain
- 10 ft extension cable (RG174) with a gold-plated connector
- Works on DC 3V to 5V (7 to 10 mA current)
Cons
- SMA male (pin) connector, so you need the right compatible port or adapter
- Best suited for RHCP GPS use, not for systems that require different polarization
What buyers think
Buyer review evidence is limited but consistently positive, with multiple comments indicating the antenna “works” and improves location performance compared to smaller or internal antennas. Reviewers also highlight practical use cases where the external antenna supports location and time synchronization, which aligns with the purpose of an active GPS antenna with a longer cable for better placement. Because the review sample is small, there is not enough evidence to draw a reliable pattern about long-term durability, real-world reception differences in every environment, or build quality beyond what the product specifications imply.
What this antenna is for
This is an active GPS antenna meant to be installed externally, typically in a vehicle or other setup where you can mount the antenna in a spot that sees the sky more clearly. The included 10 ft (3 m) cable is a practical help when you need routing room to reach your GPS receiver. The magnetic base also aims to make placement quick, especially for temporary or semi-permanent mounting on metal surfaces.
Key specifications that affect compatibility
Connector and power requirements
- Connector type: SMA male (pin). Double-check your GPS receiver’s antenna port, or confirm you can use a compatible SMA connection (or the correct adapter) before buying.
- Voltage: DC 3V to 5V, with DC current listed at 7 to 10 mA. If your system cannot supply this voltage range to the antenna, it may not power the active circuitry.
Frequency, polarization, and signal expectations
- Frequency: 1575.42 MHz ± 3 MHz (GPS L1 band).
- Polarization: RHCP (Right Hand Circular Polarization).
- Impedance: 50 Ω, VSWR listed at 2:01.
- Gain: 28 ± 3 dBic (listed as 28 dB gain with an LNA gain focus).
Pros and cons, in plain terms
Why it works well for many buyers
- Improved reception versus smaller antennas: External placement generally helps GPS locks, and buyers mention seeing more satellites versus smaller internal options.
- Install flexibility: The magnetic mount and 10 ft cable make it easier to position the antenna where it has the best view.
- Simple electronics needs: A standard 3V to 5V DC power range and a 50 Ω SMA connection make it straightforward for compatible devices.
Where buyers can get stuck
- Don’t buy it if your connector is different: SMA male is not interchangeable with most FME, SMB, or proprietary antenna connectors without an adapter.
- Power supply mismatch is a common issue: Make sure your GPS receiver or power injector provides the antenna the needed 3V to 5V DC.
Buying guide: how to choose the right GPS antenna
To decide whether this CORONIR antenna fits your setup, check three things first: (1) your GPS receiver’s antenna port type, (2) whether it can power an active antenna in the 3V to 5V range, and (3) whether you are installing for GPS L1 (1575.42 MHz) with RHCP. After that, consider placement. A magnetic mount is convenient, but permanent outdoor installs may require additional mounting hardware to prevent movement.
Verdict: is the CORONIR antenna worth it?
The CORONIR Vehicle Waterproof Active GPS Antenna is a solid pick if you need a waterproof, externally mounted GPS antenna with an SMA male connection, a 10 ft cable for routing, and active power support in the 3V to 5V range. It is less suitable for buyers whose GPS receiver uses a different connector type or cannot supply the required voltage to power the active circuitry. If you confirm those two compatibility points, the feedback pattern you will see from buyers generally supports that it can outperform smaller internal antenna solutions.
Price and availability
Pricing can change frequently. Check the current listing to confirm cost and whether the magnetic base and 10 ft cable length are the right fit for your install.
FAQ
Does this require power (active GPS antenna)?
Yes. It is specified for DC 3V to 5V operation and listed with 7 to 10 mA current, which matches its active antenna design.
What connector does it use?
It uses an SMA male (pin) connector. Make sure your GPS receiver antenna port is compatible or that you have the correct adapter.
How long is the cable?
The included cable length is 10 ft (about 3 m).
Is it waterproof?
It is described as waterproof and is designed for outdoor use, with the specifications listing a working temperature range of -40 to 85°C.
Will this work with my GPS system?
It should work for GPS L1 use (1575.42 MHz) with RHCP polarization, and it needs an SMA male connection and DC 3V to 5V power for the active antenna. If either the connector type or voltage support does not match, you may need an adapter or a different antenna.
