The MRAY is a unique solution for linking multiple analog/P25 repeater sites.

The MRAY integrates Codan’s Envoy radio, an LMR VHF/UHF 30 W Repeater and 3031 Crosspatch to create an innovative product that enables long distance communications between two or more P25 repeater sites via a HF link.

­The MRAY provides both on-site radio coverage, via the self-contained analog or P25 repeater, and long-range linking of the local communication via the included 125 W SDR Envoy HF radio. It delivers the distinct advantages of rapid deployment, ease of use, and long distance communications where previously a leased line, microwave or private IP networks were the only options.


Housed in a polyethylene weather resistant case for rapid deployment, the MRAY’s compact design enables it to be transported in passenger vehicles and commercial aircraft. The MRAY is a complete self-contained solution with optional accessories including a solar panel system, battery case, and antenna and masts.

P25 Network and Communications Extension

P25 Network Extension

When groups of people are operating in different areas separated by a large distance, each group requires local communications and may also require communications between the groups, either continuously or as needed. An MRAY will provide local communications as a VHF or UHF repeater system while also enabling the groups to communicate with each over a HF link via activation of the link on their handset. MRAY can easily be transported and re-deployed to new areas and new groups can be added to the network to allow multiple groups to communicate with each other.

P25 Communications Extension

When a command center, dispatch or central communications compound needs to keep continuous communications with a group of personnel in the field a long distance away, the field personnel deploy an MRAY and use the HF link to communicate back to the command center. The command center can then use a HF radio (or an MRAY) to create a link back to the field personnel. The field personnel do not require HF radio equipment to communicate back with the command center, using less expensive and smaller LMR handheld radios while also using the MRAY to repeat local VHF or UHF communications to each other.

Extended Communications Deployment Area

­A group of field personnel in a small area can maintain local communications while also expanding the network over long distances to other field personnel moving outside of the initial communications deployment area using an MRAY. The MRAY is used to create a local communications area with LMR equipment while crosspatching to HF in order to extend long distance communications to other field personnel using HF “manpack” radios. The HF radios can also communicate directly with each other over HF radio links created from manpack to manpack.
