HF & LMR Integrated solution
The MRAY is a unique solution for linking multiple analog/P25 repeater sites. The solution integrates Codan’s Envoy™ HF smart radio, an LMR VHF/UHF 30 W Repeater and 3031 Crosspatch™ to enable long distance communications between two or more P25 repeater sites via a HF link.
Links multiple analog/P25 repeater sites
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.
LONG DISTANCE P25
Enables long distance communications between two or more P25 repeater sites over a HF link, with no backbone infrastructure or satellite link required
LONG DISTANCE P25
SECURE COMMUNICATIONS
Configurable to different security standards for encryption over the HF and VHF/UHF links, ensuring communications remain confidential
SECURE COMMUNICATIONS
RAPID DEPLOYMENT
Easy to configure and requires only an antenna for instant communications and the linking of multiple repeater sites
RAPID DEPLOYMENT
FLEXIBLE FREQUENCIES
Easy to configure to suit any frequency requirements
FLEXIBLE FREQUENCIES
Lightweight and rugged
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.

PROBLEM SOLUTION FOR LINKING DISTANT LMR RADIO SITES
Problem: The distance between two or more local LMR radio sites can be too great for typical LMR technology to overcome, which means that the groups of subscribers associated with each site are unable to communicate with each other.
Solution: A HF link crosspatched to an LMR repeater at each site enables long distance communications between two or more local LMR sites — previously a leased line, microwaves or private IP networks were the only option. VHF and UHF cannot provide this link due to the physical nature of propagation.

Codan offers a compact solar panel package for use with its transportable radio repeater family or for use in any application requiring rapidly deployable DC power that is compact and easy to carry and set up
Battery Backup
The MRAY can operate directly from worldwide AC mains using its internal wide-range power supply. With the additional Power Case, the MRAY can operate from its self-contained power source for up to 66 hours, with recharging possible from various AC and DC sources.
Tactical 411 Broadband Antenna
The Code 411 Antenna provides excellent performance for short to medium distance HF communications. It is offered in a range of lengths to suit installation requirements. The antenna is supplied completely assembled and ready for installation.
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.
