Tallysman Offers Low Current Multi-Constellation Compact GPS Antennas

Tallysman TW4327 and TW4329 antennas.

Tallysman Wireless, Inc., is offering a family of very low power, compact, high-performance GNSS antennas for precision, commercial, and military applications.

Based in Ottawa, Canada, Tallysman Wireless,  is a designer and manufacturer of high-performance GNSS, Iridium, and Globalstar antennas and associated components.

The TW4327 and TW4329 are low-power GPS L1 + GLONASS G1 antennas that feature current consumption of 1.75 mA typically and parametrically invariant performance over a supply range from 2.5V to 12V.

The TW4327 offers a 21-dB gain minimum, and the TW4329 includes a narrow pre-filter to prevent front end saturation by near out-of-band interfering signals.

Both antennas are more tolerant to detuning effects caused by the operational environment, thanks to a 40% thicker patch element that provides wider bandwidth than conventional antennas. These antennas are also very compact (38mm x 38mm x 14.4mm), making them ideal for use in a wide range of locations.

The TW4027 and TW4029 are equivalent antennas for reception of GPS L1 signals.

“These products are ideal for any battery operated applications where low power is a pre-requisite,” said Gyles
Panther CEO of Tallysman Wireless, “and the wider patch element bandwidth will minimize detuning in non-ideal
environments, such as in covert applications.”

Tallysman Wireless has recently added an authorized distributor of its products for Russia (Aurora Mobile Technologies), and another distributor for Asia (Advanced Information Technology, Inc.), for the countries of Vietnam, Hong Kong, Singapore, China, Indonesia, and India.
