DMR Tier II Digital Repeater

Operates as a standard DMR Tier II repeater, compatible with all MOTOTRBO portable and mobile radios as well as other DMR‑compliant devices. Extends range dramatically by re‑transmitting signals with full clarity.

50W Continuous Duty Cycle

Transmits at a full 50 watts around the clock without overheating or power reduction. Designed for high‑traffic environments where the repeater is constantly in use.

Dual Slot TDMA

Doubles the capacity of a single 12.5 kHz channel by creating two virtual talk paths. Assign one path for voice and another for data, or split two independent groups — all from one frequency.

IP Connectivity & Remote Management

Built‑in Ethernet port enables remote configuration, firmware updates, and real‑time monitoring via a standard web browser or SNMP. Reduce site visits and troubleshoot from anywhere.

Extended Coverage & Unmatched Reliability

Enhances signal reach across large campuses, multi‑story buildings, or expansive outdoor facilities. Fanless convection cooling eliminates moving parts, boosting long‑term dependability.

Compact 1U Rack‑Mount Design

Fits neatly into standard 19‑inch equipment racks, taking up just 1U of space. Ideal for centralised equipment rooms and multi‑repeater installations.

IP Site Connect & Capacity Plus

Link multiple SLR 5300 repeaters over IP to create a seamless wide‑area network (IP Site Connect). Upgrade to Capacity Plus for single‑site trunking, or Capacity Max for multi‑site trunking — all via simple license upgrades.

Secure & Mixed Mode Operation

Supports both analog and digital modes simultaneously, enabling a gradual migration. Digital encryption and secure management protocols (HTTPS, SNMP v3) protect your communications and infrastructure.

Motorola SLR 5300 is the essential infrastructure component of any serious MOTOTRBO two‑way radio system. It receives signals from portable and mobile radios and re‑transmits them at higher power from an elevated antenna, dramatically improving coverage and reliability. Whether you are securing a single manufacturing plant or connecting a multi‑site campus, the SLR 5300 delivers the consistent, professional performance that Motorola is known for.

More Than a Repeater: The SLR 5300 serves as a DMR Tier II repeater out of the box. With a simple software upgrade, it transforms into a Capacity Plus trunking controller for single‑site networks, or a component in a Capacity Max multi‑site trunked system. This scalability protects your investment: start with a basic repeater and expand your network as your needs grow, without replacing hardware.

Built for Continuous Operation: The 100% duty cycle at 50 watts means the repeater can transmit non‑stop without power reduction — critical for busy channels in public safety, manufacturing, transportation, and security. The fanless design eliminates dust ingress and mechanical wear, making the SLR 5300 suitable for dusty, unmetered environments.

Easy to Deploy, Simple to Manage: The web‑based management interface and SNMP support give IT administrators full control over configuration, diagnostics, and firmware updates — even from a remote location. Automatic software updates and remote monitoring reduce the need for on‑site maintenance visits, saving time and operational costs.

Why Choose Motorola SLR 5300? Because a professional two‑way radio system is only as strong as its backbone. The SLR 5300 provides that backbone with rock‑solid reliability, future‑proof scalability, and the full backing of Motorola’s engineering expertise. It comes with a 2‑year manufacturer warranty and dedicated local support from Electro Creators across Maharashtra, Madhya Pradesh, and Chhattisgarh. We offer site survey, installation, antenna system design, and network configuration.
