Hytera E-pole200 VHF - Dual-channel DMR Ad-hoc Repeater

The Hytera E-pole200 is a DMR ad-hoc dual-channel repeater designed to quickly build multi-hop narrowband networks using wireless interconnection technology. It operates without any IP links such as fiber optics or microwave connections. The repeater can simultaneously repeat voice services on two channels and is compatible with both Hytera and third-party DMR Tier II radios. Its flexible design allows installation on poles, such as lamp posts, or on walls, such as building exteriors.

Automatic networking
Up to 31 repeaters can automatically interconnect without relying on IP infrastructure. The network remains operational even if one or more repeaters fail, ensuring high resilience.

Flexible installation
The all-weather design allows the repeater to be mounted on poles or walls without requiring existing infrastructure such as equipment rooms.

High compatibility
The repeater supports Hytera and third-party DMR Tier II radios, as well as Hytera first-generation ad-hoc networking products.

Multiple power supply options
The repeater can be powered by batteries, solar energy, or a trunking base station using a −48 V supply, making it suitable for a wide range of deployment scenarios.

LTE connectivity for remote dispatch
Through a public LTE network, the repeater can connect to command and dispatch systems without distance limitations.

Extended communication range
When installed at high altitude, the repeater can achieve transmission distances exceeding 50 km with its 10-watt output power. With a SIM card installed, it can create networks over even longer distances and communicate directly with mobile phones.
