Product description
GNSS-TW-3742-ANT is a Tallysman TW3742 multi-constellation antenna supplied by Roger-GPS for GNSS repeaters. Accutenna technology provides circularly polarised reception across the full band, giving superior multipath rejection. An additional pre-filter protects against near-frequency and strong harmonic signals.
