M2M Connectivity has added a helical Maxtena M1227HCT series multiband GPS antenna to its product range.
The device uses Helicore technology to achieve an upper-hemisphere efficiency greater than 40% in both L1 and L2 GPS bands and typical axial ratio performance of 0.5 dB over the entire upper hemisphere.
The small 30 (base) x 50 mm (height) size and lightweight features make the antenna suitable for airborne applications to precision surveying equipment.
Unlike traditional GPS patch antennas, the M1227HCT requires no ground plane to achieve its performance.
Coupled with an integrated wideband LNA, the antenna achieves +16 dBic performance in both GPS L1 and L2 bands. The Helicore technology enables it to operate in the most extreme and demanding applications giving maximum satellite reception, ultra-low dilution of precision (DOP) and decimeter accuracy.
The interface connector is available in SMA with a TNC option.
