FAQ

Q: Is this antenna compatible with 4G LTE networks?
A: Yes! It covers 700/1800MHz bands (common for 4G LTE), making it ideal for modern routers/modems.

Q: Can I use it with a non-magnetic surface?
A: Use adhesive metal plates (sold separately) for fiberglass/plastic surfaces.

Q: Does the SMA male connector fit standard routers?
A: Absolutely—it pairs with SMA female ports on most 3G/4G devices.

Q: Is the cable waterproof?
A: The antenna base is weather-resistant, but we recommend sealing the cable joint if exposed to heavy rain.

Q: How strong is the magnet?
A: Holds securely on moving vehicles at 80+ km/h. Tested for 2hrs under intense vibration.

Q: Will this work for GSM networks?
A: Yes! It supports 900/1800MHz GSM bands for calls/SMS.

Q: What’s the warranty period?
A: 1-year warranty against manufacturing defects.

Q: Can I shorten the RG174 cable?
A: Not advised—cutting may impair impedance matching. Use as-is for optimal performance.
