GNSS antennas are a critical but often overlooked part of a receiver setup. Choosing a correct antenna is hugely important since antennas are the main interface between the GNSS space segment and the user, as they capture the L-band signals transmitted by satellites. Antenna must be able to convert the energy in the electromagnetic waves arriving from the satellites into an electric current that is further processed by the receiver. Given that signals received from GNSS satellite are weak and arriving from any direction, it is clear that choosing the correct antenna is imperative. Choosing the optimal GNSS antenna for the application will maximize GNSS receiver’s positioning performance.

NVS Technologies provides a wide range of high quality antennas to suit a wide variety of applications and markets. To access the product specific page, please click on the corresponding receiver below.

GPS L1 / GLONASS Timing Antenna with Integrated Lightning Protection

Antenna with Integrated Lightning Protection
The GPSL1GL-TMG-40N timing reference antennas are specifically designed for long-lasting, trouble-free deployments in congested cell-site applications. The low noise, high gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs.

    Antenna with Integrated Lightning Protection
    The GPSL1GL-TMG-40N timing reference antennas are specifically designed for long-lasting, trouble-free deployments in congested cell-site applications. The low noise, high gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs.
    The proprietary quadrifiliar helix design, coupled with multistage filtering provides superior out-of-band rejection and lower elevation pattern performance than traditional patch antennas.
    Their unique radome shape sheds water and ice, while eliminating problems associated with bird perching. The antenna may be purchased by itself or with pipe mounting hardware. Custom models or site kits options are also available.
    This antenna is made of materials that fully comply with provisions stipulated by EU directives RoHS 2002/95/EC.
    The antenna provides integrated lightning protection capability.
    The antenna also features ESD, reverse polarity protection and transit
    voltage suppression.
