Tallysman’s TW4027 benefits from:
Longer battery life
Excellent signal to noise ratio
Ideal for harsh environments
Excellent out of band signal rejection
TW4027 is amongst the lowest power devices available, requiring a typical current consumption of just 2 mA. TW4029 still performs with an excellent noise figure. These features result in TW4027 being ideally suited for battery operated fleet and tracking applications.
Tallysman’s TW4027 supports 1 dB RHCP received power across the full frequency. Additionally, the TW4029 has a dual stage Low Noise Amplifier (LNA) with a mid section SAW that supports a great axial ratio across the full frequency.
In addition to the above TW4027 is housed in an industrial grade weather proof enclosure that can be surface mounted via magnet, screws or adhesive material.
LNA Pre-filter Available
TW4029 provides additional benefits with a LNA pre-filter.
