TW2600 Magnet Mount Iridium™ Certified Antenna
The TW2600 by Tallysman Wireless is a
professional grade, magnet mount, passive
right hand circularly polarised antenna for the
1616 to 1626.5 MHz frequency band, certified
and specially designed to maximise the
performance of Iridium™ Voice and Data
Modems.
The TW2600 features a high performance dual-
feed patch element that provides great axial
ratio (3dB max) over the entire Iridium™
frequency band, thus signals at the band edges
remain truly circular, unlike the response of
single feed antennas.
The TW2600 is housed in a compact, industrial-
grade weather-proof, magnet mount enclosure,
with threaded base holes for screw down
attach. It is available with a 50 cm cable,
allowing for the Iridium™ Modem to be
mounted out of the elements and reach, and
still providing excellent Iridium™ signal
coverage.
