The TW1600 employs Tallysman’s unique
Accutenna™ technology in a low cost OEM dual feed,
passive Right Hand Circularly Polarized antenna
(RHCP) for the 1616MHz to 1626MHz frequency
band, specifically designed to enhance the signal to
noise ratio of communications over the Iridium™
satellite communications network.
The wideband dual feed patch element in the
TW1600 has an excellent axial ratio across the entire
Iridium™ bandwidth. Unlike single feed antennas, the
TW1600 provides excellent multipath rejection and a
truly circular transmission response across the
Iridium™ band.
The TW1600 includes a built-in 35mm circular
ground plane but best performance is obtained with
this augmented with a local system ground plane or
reflecting surface equivalent to 100mm diameter (DC
connection not required).
OEM antennas are easily detuned by the local
environment. Tallysman offers custom tuning services
for optimized integration into OEM end-user modules.
