Tallysman TW4037 Benefits from:
Longer battery life
Excellent signal to noise ratio
RoHS compliant
Ideal for harsh environments
Excellent out of band signal rejection
Featuring a precisely tuned, single feed patch element that achieves 40% wider bandwidth than competitive antennas, the TW4037 supports 1 dB RHCP received power across the full frequency. Additionally, the TW4037 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.
Tallysman’s TW4037 is housed in an industrial grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
For a very low power, low gain prefiltered antenna Tallysman are pleased to provide the TW4039.
TW4037 is amongst the lowest power devices available, requiring a typical current consumption of just 5.5 mA with constant characteristics over supply voltages from 2.5V to 16V – yet it still performs with an excellent noise figure.
