Molex Flexible GNSS Antenna - U.FL (Adhesive)

The Molex GNSS Flex antenna is a great option for basic GNSS applications and will work with any of our GNSS boards equipped with a U.FL at a fraction of the cost of many of its big brothers. This antenna supports GPS, Galileo, BeiDou, and GLONASS in three different frequency bands (1561 +/-3MHz, 1575 +/-3MHz, 1602 +/-3MHz).

The Molex Flexible GNSS Antenna has an incredibly small footprint at 40.40mm x 15.40mm, while the adhesive pad is a bit bigger at 56.40mm x 20mm. Even better, the antenna is only 0.1mm thick (or about the thickness of a piece of paper). Simply remove the backing and stick this to any surface, or leave the backing on (just be careful of the fragile U.FL connector).

  • Cable length: 50mm
  • Connector: U.FL
  • Radiation Pattern: Omnidirectional
  • Polarization: Linear
  • Weight: 0.466 g
  • Mounting Style: Adhesive
  • Protocol: BeiDou, Galileo, GLONASS, GPS
  • Return Loss: < -8dB
  • Peak Gain (Max): 1.1 dBi+
  • Efficiency: >74%
  • Input Impedance 50 Ohms

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

No reception with this one

by verified purchaser

Tried this antenna with a Neo M8U and had no luck getting any satellite connections. At first I though the M8U was broken or there were some configuration issues but as soon as I changed it to an active antenna (GPS-17099) it worked like a charm!

Pro: smallish footprint, price Con: does not work :-/
