## TW1010/TW1012 Embedded GPS L1 Antenna 

The TW1010/TW1012 is low cost, high gain, high performance, embedded GPS L1 antenna, specially designed for OEM industrial, military, precision positioning and timing applications. 

The TW1010/TW1012 features a precisely tuned single feed ceramic patch element.  It has a two stage Low Noise Amplifier (LNA) with a mid-section SAW.   An optional tight pre-filter is available with part number TW1012 to protect against saturation by high level sub-harmonics and L-Band signals. 

## TW1010/TW1012 Dimensions with RG174 cable (mm) 

The TW1010/TW1012 covers the GPS L1 and SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception, multipath rejection and out of band signal rejection. 

The TW1010/TW1012 has a built-in 35mm circular ground plane that can be augmented with host system ground surfaces.  Patch Elements are susceptible to detuning by the local environment. Tallysman offers custom services to assist with integration of OEM modules into an end user solution. 

Custom cable lengths and connectors are available.
