T-3740 Permanent-Mount Multi-GNSS Timing Antenna

Multi-GNSS GPS Timing Antenna

TimeTools Multi-GNSS timing antenna systems feature class-leading out-of-band signal rejection with great signal to noise ratio. They also have a very high LNA gain, ideal for long cable runs typically used in permanent-mount timing applications.

Additionally, unlike some competitors, TimeTools Multi-GNSS antenna systems do not include an integral receiver in the antenna enclosure. The receiver is enclosed within the time server, thus protecting it from harsh weather conditions, aiding long-term reliability.

Long Cable Runs


The T-3740 is a professional grade, high gain, pre-filtered permanent mount, multi-constellation antenna. It is housed in an industrial grade, weather-proof, conical white enclosure, and is supplied with a TNC Jack (female) connector. The antenna features a conical radome and is specially designed for timing applications in environments characterized by high L-Band RF fields and long cable runs. The T-3740 also features a precisely tuned ceramic patch element, a tight band-pass SAW pre-filter, a first LNA gain stage, an in line SAW filter, followed by a two stage amplifier.

The antenna provides a reliable and clear multi-constellation signal while minimizing loss-of-lock, even when conditions are less than ideal. It covers the GPS L1, GLONASS G1, BeiDou B1, Galileo E1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1559 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time.

An optional specially designed right-angled bracket is available for securely mounting the antenna on to a vertical surface, such as a wall, or antenna pole (P/N MT4-GPS).
