Tallysman® introduces the light-weight twin band GNSS and passive Iridium helix antennas HC843 and HC843E
Tallysman® Wireless Inc. announced the addition of two new models to its industry-leading line of helical antennas.
The main feature of the HC843 and HC843E is two-mode operation. The first mode is dual frequency GNSS and the second is passive Iridium ™ (1616.0-1626.5 MHz), which supports both voice and data communications. The antenna operates in GNSS mode when its input voltage is less than 5.5 VDC and in Iridium mode when it is more than 5.5 VDC.
The helix antennas embedded in the HC843 housing and in the HC843E are designed and built for high-precision positioning in a very light and compact form factor. They are therefore ideal for many applications including autonomous vehicle navigation (land, sea and air), hand-held land surveying devices, vehicle positioning and GNSS timing among others. Both models support GPS / QZSS-L1 / L2, GLONASS-G1 / G2, Galileo-E1 and BeiDou-B1, including WAAS (North America), EGNOS (Europe), MSAS (Japan) and GAGAN (India).
The HC843 is 44 mm wide and 62 mm high and weighs only 42 g. It features a precisely tuned helical element that provides excellent axial relationship and operates without the need for a ground plane, making it ideal for a wide variety of high-precision applications. The HC843 also features a low-current, low-noise amplifier (LNA) with pre-filter to prevent harmonic interference from high-amplitude signals such as 700 MHz band LTE and other nearby in-band cellular signals. The HC843 is housed in a robust, military-grade IP67 plastic housing. The antenna base has an integrated SMA connector, a waterproof O-ring and three screw holes for secure attachment.
