The TW3865 employs Tallysman’s unique Accutenna™ technology covering the GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1 and SBAS (WAAS, EGNOS & MSAS) frequency bands. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. The TW3865 offers excellent axial ratio and a tightly grouped phase center. This antenna sets a new price/performance standard in its category. (Previous model TW3805). TW3867 is with pre-filter.
TW3865支持GPS L1/L2, GLONASS G1/G2, 北斗B1,Galileo E1和SBAS (WAAS, EGNOS & MSAS).
The OEM TW3865 is supplied with a standard 60mm diameter circular ground plane, with a coaxial cable terminated with a connector (right angle MCX is shown in the drawing). Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.
The TW3865/TW3867 is REACH and RoHS compliant.
