It features a small patch element with 40% wider bandwidth than typical GPS L1 antennas. The TW4020 features a high performance custom tuned ceramic patch element, 15 KV ESD circuit protection, a high gain two-stage low noise amplifier (LNA) with a mid-section high rejection SAW filter. It covers the GPS L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception. Even with the wider bandwidth, the TW4020 antenna is among the smallest high performance antenna available. It is housed in a compact IP67 magnetic mount enclosure. ## **Applications** - Cost Sensitive Positioning - Fleet Management & Asset Tracking - Covert surveillance ## **Features** - 40% wider bandwidth, small footprint - Axial ratio: 6 dB max (GPS ) - Low noise LNA: 1 dB - High rejection SAW filter - High gain: 28 dB typ. ## **Benefits** - Increased system accuracy - Excellent signal to noise ratio - RoHS compliant - Ideal for harsh environments - Excellent out of band signal rejection - Wide voltage input range: 2.5 to 16 VDC - IP67 weather proof housing ## TW4020 Wideband GPS Antenna ## **Specifications** ## **Antenna** Architecture Wideband Single Feed Patch 1 dB Bandwidth 31 MHz 10dB Return Loss Bandwidth 45MHz Antenna Gain (with 100mm ground plane) 4.5 dBic Axial Ratio over Bandwidth (over full bandwidth) 4dB @ Fcenter, 6 dB max ## **Electrical** Architecture LNA stage 1 -> SAW filter-> LNA stage 2 Filtered LNA Frequency Bandwidth 1565 to 1585 MHz Polarization RHCP Gain 28dB min., 1575.42 MHz Gain flatness +/- 2 dB, 1575 to 1606 MHz Out-of-Band Rejection <1500 MHz -45dB (typical) <1550 MHz -25dB (typical) >1640 MHz -40dB (typical) VSWR (at LNA output) <1.5:1 Noise Figure 1 dB typ.
