## **TW3012 permanent-Mount GPS-L1 Antenna** 

**Frequency Coverage: GPS-L1** 

The TW3012 is a professional-grade, permanent-mount GPS-L1 antenna, specially designed for precision tracking and timing applications. 

The TW3012 features a custom high performance, wide band patch element, a 28 dB gain LNA stage and a high-rejection out-of-band SAW filter. The TW3012 includes a tight SAW pre-filter to provide strong protection against out-of-band signals. It provides ±10 MHz bandwidth centred on 1575.42 MHz and covers the GPS-L1, and SBAS (WAAS/EGNOS/MSAS) signals. It provides great axial ratio, excellent circular polarized signal reception, strong multipath rejection and very deep out-of-band signal rejection. 

The TW3012 is housed in a permanent-mount industrial-grade weatherproof enclosure. Optional components include a 10 cm ground plane (P/N 23-0067-0), an L-bracket mount (P/N 23-0040-0), or a pipe mount (P/N 23-0065-0). 

## **Applications** 

- Mission-critical GPS tracking and timing 

- Precision agriculture, mining, and construction 

- Law enforcement and public safety 

- Fleet management and asset tracking 

- Avionics 

## **Features** 

- Great axial ratio 

- Low noise LNA (4.3 dB typ.) 

- Pre-filter 

- High-rejection SAW filter 

- High-gain (28 dB typ.)
