Ottawa, Canada –Tallysman Wireless, a provider of high performance, high quality RF and GNSS components and wireless telematics solutions, announced the release of the TW33XX family of wideband GPS L1/GLONASS antennas.

The TW33XX series features a patch element with 40 percent wider bandwidth than typical single feed patch antennas so that the GPS-L1 and GLONASS signals are included in the 1dB received power bandwidth of the patch antenna.

The family includes a LNA with a 1dB NF, and with either 40dB or 28dB gain. Both gain versions are available with optional brick-wall pre-filters to protect against saturation by high level sub-harmonics and L-band signals. The entire product family features a 2.5V to 10V operating supply range and meets all requirements for newer high performance GPS chip-sets and receiver types.

Other features include robust IP67 compliant housings with a white metal base, double panel mount nuts and an optional L-bracket for fixed mounts.
