Datasheet:Overview
Tallysman’s HC977 is a lightweight precision-tuned helical antenna with frequency coverage L1/L2/L5/G1/G3/E1/E5/B1/B2/B2a + L-band. It includes an integrated low-loss pre-filter to protect against harmonic interference from high amplitude interfering signals, such as 700 MHz band LTE and other near in-band cellular signals.The HC975 antenna is also available in an embedded version; the HC977E.
