Product description
GNSS-TW-3872-ANT is a dual-band Tallysman TW3872 antenna supplied by Roger-GPS for L1/L2 GNSS applications. It features a precision-tuned, dual-feed stacked patch element with excellent axial ratio and tightly grouped phase centre variation.
The antenna pre-filter increases its immunity to high-amplitude interfering signals such as LTE and other cellular signals. Multipath rejection and signal-to-noise ratio are excellent.
