The
TW2743
employs
Tallysman’s
unique
Accutenna technology in a magnet mount, right
hand circularly polarized antenna for the reception
of all, of the GNSS constellations (GPS L1/GLONASS
G1/ Galileo E1/ BeiDou B1, 1559-1606 MHz) plus
Iridum: 1616 to 1626 MHz frequency bands. It is
specially designed to maximize the performance of
Iridium™ Voice and Data Modems plus the upper
GNSS band (1559 – 1606MHz)
The TW2743 is switchable between the passive
Iridium and the active GNSS antenna by changing
the input voltage to the antenna. When the input
voltage is less the 5.5VDC (around 5.2 VDC), the
antenna will engage the GNSS antenna. To invoke
the passive Iridium antenna, an input voltage
above 5.5VDC (around 5.8 VDC) is required.
The TW2743 features a high performance dual-
feed patch element that provides great axial ratio
(4.5dB max, <1.5dB @ zenith) over the entire
Iridium™ + upper GNSS frequency band, thus
signals at the band edges remain truly circular,
unlike the response of single feed antennas.
The TW2743 is housed in a compact, industrial-
grade weather-proof, magnet mount enclosure,
with threaded base holes for screw down
attachment.
