Hytera GPS04 Vehicle GPS Antenna for Mobile Radios (SMA, 1575 MHz)
The Hytera GPS04 is the OEM vehicle GPS antenna for Hytera mobile radios with GPS positioning. It receives the GPS L1 signal at 1575 MHz over an SMA connector and a 3-meter cable — long enough to route from the vehicle roof to a dash-mounted radio. For fleets running location reporting, it gives the radio a clean sky view that an in-cab install can't.

Why Professionals Choose the Hytera GPS Antenna GPS04
A mobile radio is typically mounted on the dashboard or inside the vehicle’s cab. This placement makes it difficult to obtain location data, leading to inaccuracies or a complete lack of data. For a dispatcher tracking a delivery fleet or a security patrol, this means that vehicles are displayed in the wrong location on the map or not displayed at all. The GPS04 automotive antenna for the GPS receiver is mounted on the roof or along the window line, where it has an unobstructed view of the satellites.
The Hyt GPS04 receives the GPS signal in the L1 band at a frequency of 1575 MHz via a standard SMA connector. The antenna comes with a 3-meter cable, which is usually long enough for a direct connection to a mobile radio unit located in the cab or trunk. The antenna element is a dielectric patch tuned to the L1 band. This is the type used in automotive GPS navigators, as opposed to the whip and short antennas used for voice radio communication.
The GPS04 uses a magnetic-base mount, so it sits on a vehicle roof or trunk lid and can be repositioned without drilling, with its 3-meter cable running down to the radio. Exact specifications can change with production updates, so confirm the current mounting, connector, and fit for your radio with your seller or a Hytera representative before ordering. As an authorized Hytera dealer, AXDIGITAL can verify the right GPS04 configuration for your fleet and supply the OEM part.

FAQ
Is the GPS04 compatible with mobile radios other than Hytera?
The GPS04 uses a standard SMA connector and receives the standard GPS L1 signal at 1575 MHz, so in principle it can work with another manufacturer's mobile radio that has a matching SMA GPS antenna input. Compatibility isn't guaranteed, though: it's an active antenna that needs a suitable bias voltage from the radio's GPS port, and both the connector type and the supplied voltage can differ between brands. Hytera specifies and supports the GPS04 for its own mobile radios and does not warrant it for other brands.
Which teams or working conditions call for the GPS04?
The GPS04 is designed for operations that require real-time tracking of vehicle radios. These may include: fleets of logistics and delivery companies, security patrols, public safety units, as well as construction equipment and utility vehicles. The use of a GPS antenna is particularly important when a mobile radio is installed under the dashboard or in the trunk. That is, when the built-in GPS receiver does not have sufficient line of sight to the sky for reliable transmission of location data or automatic vehicle location (AVL). Mounting the antenna on the roof rail provides more accurate and stable coordinates for route planning, calculating response times, and ensuring the safety of lone workers.
