Hytera DAM1575A2 Magnetic Mobile GPS Antenna

The Hytera DAM1575A2 Mobile GPS Antenna is designed for reception centred on 1575.42 MHz within a defined band, using a magnetic base to support planned positioning on a suitable surface. It combines an SMA connector with a 3 m RG174 cable, giving fleet, facilities, and operations managers clear interface and routing checkpoints before installation. Inside the black housing, an LNA provides 28 dB typical gain without the cable, and the antenna operates from 3-5 V. The buying decision therefore involves more than the mount style: frequency, connector, power requirements, and installation space all need to match the host equipment. This defined role positions DAM1575A2 as an accessory for mobile GPS deployments rather than a general antenna selected by brand alone.

Hytera DAM1575A2 Mobile GPS Antenna Signal Profile

DAM1575A2 operates around a centre frequency of 1575.42 MHz with a ±3 MHz tolerance and ±5 MHz bandwidth. Its impedance is 50 Ohm, while VSWR is stated at 1.5:1. These values give communications technicians a specific matching set when reviewing the host equipment input. Frequency, impedance, and standing-wave ratio can be compared before the antenna is physically fixed in place. RHCP polarisation is also part of the signal identity that should be considered when confirming the antenna against the intended GPS system requirements.

Peak gain is greater than 3 dBic when measured with a 7 × 7 cm ground plane. That qualification matters to a deployment decision because the gain figure is tied to a stated arrangement rather than standing alone as an unconditional number. When comparing the unit with another antenna, the technical team should retain that relationship and review the mounting or ground-plane context alongside the gain. The LNA provides 28 dB typical gain without the cable, with a noise figure of 1.5 dB.

Power and Host-Equipment Connection

The antenna circuit requires 3-5 V DC and draws 5 mA, with 10 mA maximum. This creates a direct engineering check: the host device associated with the SMA connection should be reviewed for compatible interface and power delivery before quantity is ordered. Connector shape alone is not enough to establish deployment fit, so voltage and current need to remain part of the approval. Retaining those values on the internal item identity also helps stores and maintenance teams direct the antenna to the correct equipment platform.

The connection reaches the host through a 3 m RG174 cable. This length gives the installer room to position the magnetic base separately from the device, but the entire route should be planned before fixing the antenna. The team can measure the actual path, identify cable transitions, and make sure the SMA connector reaches without tension. These steps turn the stated cable length into a manageable installation boundary and reduce the chance of discovering an unsuitable route after the mounting position has already been selected.

Physical and Environmental Deployment Fit

The DAM1575A2 housing measures 48 × 39 × 16 mm, weighs less than 110 g, and is black. Those limits help an equipment manager review the available area on the intended surface and the space around the cable exit. A placement trial can be completed before the location is approved, followed by checks for cable reach and access to the SMA connector. Because the base is magnetic, surface suitability remains part of the deployment decision and should be assessed together with stability and service access.

Its operating-temperature span is -40°C to +85°C, and the stated humidity range is 95%-100% RH. The unit is also described for fully waterproof working. These characteristics support planning for vehicles, mobile equipment, and field locations across varied Saudi operating environments while site-specific installation procedures remain in force. RoHS and REACH compliance provide two additional identifiers that procurement teams can include in internal requirement reviews alongside the electrical, frequency, and connection details.

Saudi Fleet and Field Use Cases

DAM1575A2 serves organisations adding a mobile GPS antenna to equipment with an SMA input and compatible power delivery. In fleet management, the base can occupy a suitable surface while the RG174 cable follows a planned route to the device inside the vehicle. For field-service or facilities teams, its compact housing and limited weight allow it to be considered where a large accessory would complicate the equipment arrangement, with frequency and electrical compatibility remaining the primary acceptance criteria.

Security and operations teams can make receiving more consistent by keeping DAM1575A2, 1575.42 MHz, SMA, and the cable length together on the purchase order. A technician can then confirm voltage and current, inspect the base, measure the route, and connect the unit to its assigned device. This sequence reduces the risk of issuing a GPS antenna to a platform with a different interface and gives both the asset custodian and technical team a clearer path from stores receipt to installed equipment.

DAM1575A2 Versus Its Hytera Family Sibling

DAM1575A2 is positioned as a powered mobile GPS antenna centred on a defined frequency and using an SMA interface. AN0358M33 is its named family sibling, but that model addresses a different radio-antenna requirement and is not a direct substitute for DAM1575A2. The correct comparison starts with function. When the platform requires the GPS reception role and interface associated with DAM1575A2, the team can then review power, cable, and mounting fit. A shared manufacturer does not make the signal role or connection method interchangeable.

This distinction gives DAM1575A2 a clear place in the accessory family. It brings GPS reception characteristics, an LNA, magnetic mounting, RG174 cable, and an SMA connector into one unit. The buyer needs to balance positioning convenience with the electrical interface, cable route, and surface requirements. When those elements match the host equipment, the product can move into deployment under a defined plan. Any mismatch should be resolved before installation rather than after the antenna has been issued to the site.

Specification-Grounded Inspection and Rollout

Inspection can begin by matching DAM1575A2 on the package and item card, then confirming the SMA connector, RG174 cable, and magnetic base. The technician can review the host input against 50 Ohm, 3-5 V, and the stated current requirement before identifying a suitable surface and a route within the available cable length. Space can be reserved for the complete housing, while the ground-plane arrangement tied to the peak-gain value is considered during technical evaluation.

After a trial installation, the team can check base stability, cable tension, and connector access, then associate the antenna with its host device and deployment location in the asset record. Fleet operations can repeat the same sequence for each installation while keeping a consistent model, connection, and power checklist. In this way, DAM1575A2 specifications become operational checkpoints that guide the purchase decision, support controlled rollout, and keep later maintenance tied to the correct GPS antenna.
