The M1575HCT-22P from Maxtena is a passive antenna that operates in the GPS L1 band. It is built on Helicore technology that provides exceptional pattern control, polarization purity and high efficiency in a very compact form factor. The antenna weighs only 2 grams and is ideal for the most demanding, mechanically constrained platforms including handheld devices, asset tracking, seismic recording instruments. This antenna requires the sale of service ahead of the sale of antenna, such as feasibility studies, prototyping, and chamber measurement. The antenna is mounted on the inside of the applications housing, allowing it to be hidden. The antenna element is custom tuned to the applications enclosure.
