Repeaters

A REPEATER is utilized to enhance the range of lower-powered portable and mobile radios.  Typically a Repeater is strategically placed (and licensed by the FCC) at a fixed location and antenna height which will provide a larger area of coverage (or "footprint").  Repeaters may be installed to cover single or multiple buildings or placed high on a tower (or existing structure "farmers" grain leg for example) to best meet the client's needs.

 

In many cases, "Engineered Propagation Models" are created to predict the area of coverage expected from a known frequency, height, and antenna.  These take into consideration many factors including, terrain, vegetation, type of area (urban, forested, rural, etc) and other factors that will affect radio range/coverage footprint.  JES provides in-house engineering and Propagation Models to eliminate contracted services of the type.

 

Repeaters are utilized in Low Band (30-50Mhz), High Band (VHF) 150-170Mhz, UHF (450-470Mhz) as well as in the 700-900Mhz bands.

 

Repeaters may be stand-alone for a single site or NETWORKED together to provide a WIDE-AREA-COMMUNICATIONS-NETWORK (WACN).

 

JES provides: multiple types of single-site and WACN radio solutions to fit our client's needs.

 

TRANSPORTABLE REPEATERS are customized "systems in a deployable weather-proof case" which may be deployed within minutes to the scene of an EMERGENCY!  These include ALL of the required components for a battery/mobile operation complete with roller-case, repeater, battery(ies), and antenna system in a package.  These items are COTS (Common-Off-The-Shelf) from the manufacturer or JES.
