Antennas

If you want to use the RasPiGNSS expansion board for PPP or RTK applications, you need to make absolutely sure to get the most from satellite signals available, thus using a quality antenna capable of receiving GPS, GLONASS, and SBAS signals is strongly encouraged.

In our tests with the RasPiGNSS module we tested both no-brand stock GPS antennas as well as high-gain quality GPS/GLONASS antennas from Tallysman. Our tests indicate that quality antennas like the Tallysman TW-4421 or TW-2410 outperform standard GPS antennas by far, regarding both signal strength and fix quality.

We are now able to provide these two recommended Tallysman antennas in our webshop for your convenience.

Tallysman™ TW-2410

GNSS antenna covering the GPS L1, GLONASS G1 and SBAS (WAAS, EGNOS & MSAS) frequency band. It is especially designed for precision industrial, agricultural and military applications and offers excellent circular polarized signal reception, multipath rejection and out of band signal rejection. It is ideal for use in Precise Point Positioning (PPP) systems which require only a single frequency. With its large patch element of 57mm diameter it offers excellent SNR and signal quality even in adverse reception environments like tree canopy etc. Delivered with 5m cable and SMA male connector suitable for the RasPiGNSS module. Please see the Tallysman TW-2410 product page for detailed specifications or download the data sheet directly.

TLM-TW-2410, Tallysman TW-2410 GNSS antenna, EUR 104.00 p.pc. excl. VAT

Tallysman™ TW-4421

Low-cost, small form-factor, dual-feed GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) magnetic mount antenna. Due to its novel dual-feed wideband patch element it provides excellent multipath rejection capabilities, and is therefore best suited for mobile applications in complex urban environments (urban canyons, etc.). Delivered with 3m cable and SMA male connector suitable for the RasPiGNSS module. Please see the Tallysman TW-4421 product page for detailed specifications or download the data sheet directly.
