Tallysman GNSS has added three new antennas to its Helical antenna line.
Released earlier this year, the helical antenna line provides unprecedented performance in a lightweight, compact form factor.
The line now extends beyond dual-band GNSS and Iridium support to also include single and triple GNSS frequency bands.
Tallysman helical antennas are designed for applications that require high performance and versatility, with an absolute minimum of weight, such as unmanned aerial vehicles (UAVs).
In addition to the HC600, HC871 and HC872, the expanded helical antenna family now includes:
the single frequency HC771
the dual- frequency (plus L- band corrections) HC882
the triple band (plus L- Band corrections) HC975.
The table below lists the complete Tallysman helical Family of antennas.
