Multiband Subtillo Mini 628i


The Subtillo 628l MINI is the perfect antenna solution for the Marine Buoy and Drifter producers wanting to use an off-the-shelf IRIDIUM/GPS or Globalstar/GPS antenna design to fit inside a 4” drifter pipe.

The antenna is a variant of the very successful Subtillo Solo Iridium only antenna. Using the same highly efficient 3.2mm board and a GPS ceramic patch, we machine the antenna to 9cm diameter, drill out 2 finger positoning holes and solder 2 X UFL cables on the underside.

The result is a high quality, high performance and mechanically sturdy antenna.
