Tallysman’s TW2920 is a wideband multi-constellation/L-band antenna equipped with Accutenna technology. It delivers incredible performance in a small, compact form factor just under six centimetres in diameter with incredible multipath rejection, tight phase centre variation, and linear phase response. It also features a dual-feed wideband path element and a pre-filter and LNA which work together to ensure a superior signal-to-noise ratio without any loss of signal integrity.

Housed in a weather-resistant plastic radome and available with a variety of mounting options, The TW2920 is perfect for a range of applications where precision is key, such as agriculture, machine control, and vehicle guidance. With powerful shielding from sub-harmonic and near-frequency signals (such as Wi-Fi), as well as multipath rejection, it can be used in urban environments without fear of interference.
