How Do Radio Repeaters Work ?
Repeaters help with the problem of line of sight in conventional communications. If two radios want to communicate with a hilltop in the way, then there is no line of sight. One way to overcome this is placing a repeater (or base station) at the top of the hill. One radio communicates up to the repeater, this is called uplink, and then the repeater repeats that transmission down to the radio on the other side of the hill, this is called downlink.
We Build Extreme Radio RepeatersFor use in Survival, Aviation, Marine, Construction & Remote Camps.

VHF/UHF Emergency RepeatersBasic Repeater Package Basic Stuff That Works !
Where and When You Need It !
When your life and the lives of others depends on your communications, why compromise?
The TRP-9000 Survivalist is built for everything required for Tactical Emergency Radio Repeater Coverage.
The TRP-9000 series of portable repeaters operate Analog Conventional and can be rapidly deployed to provide instant local or networked radio communication solutions. This nifty gear is all you need in an emergency.
The TRP-8000 is built, using best of class radio equipment & world-class Sinclair Duplexers - all built inside a lunch box sized, genuine 40MM US Ammunition Can, that provides robust protection from dust, dirt, corrosion and most importantly, interface from outside sources. In fact, the TRP-8000 provides more protection than any other commercially available product on the market today! Designed to meet IP67 standards, the TRP-8000 can withstand the harshest operating environments. Capable of delivering between 5W and 25W of output power, the 8000 can run for over 48 hours at a 40% transmit duty cycle at max power from a standard car battery.

Built Tough - Portable VHF Marine Repeaters
NEW! 6 Channel Duplex Talk Channel Capability 26,27,28 & 83,84.85
VHF Marine Repeaters Provide Coverage on Marine Repeater Channels as well as Crossband coverage for Land Mobiles and Land Based Stations.
These systems are designed for Offshore operation in the South Pacific, South East Asia, Central America and South America, where the need for access to Marine Repeaters as well as linked Marine to Land services are critical for effective safety communications.
We build different designs to suit your needs; these include Transportable or Fixed Station.
VHF Marine Repeaters help to increase the distance that Standard VHF Marine services can communicate through pre-programmed repeater channels. These channels include International duplex channels 78, 79, 80, 81, 82 and 83. Through the use of Marine Repeater Channels, a weak station would be amplified through the repeater and back to the end units.
Choose a Cross-Band repeater to link various services that operate in different bands. For example, a Search & Rescue team operating on UHF needs to communicate with a fire department on UHF.
The TRP-8000-X is built, using best of class radio transceivers & world-class Sinclair Duplexers - all built inside a lunch box sized, genuine 40MM US "Ammunition Can" that provides robust protection from dust, dirt, corrosion and most importantly, interface from outside sources. In fact, the TRP-8000-X provides more protection than any other commercially available product on the market today! Designed to meet IP67 standards, the TRP-8000-X can withstand the harshest operating environments. Capable of delivering between 5W and 25W of output power, the TRP-8000 can run for over 48 hours at a 40% transmit duty cycle at max power from a standard car battery.
Mountaintop 
Repeaters and Fixed station repeaters provide a stable platform for long term, long distance coverage using higher than normal power output and fixed station antennas that are usually mounted on a tower, or atop a building. Most common mountaintop repeaters operate from a stationary power generator, or solar power, as the case may be. In most instances, mountaintop sites are built in communications shelters, or shipping containers to protect the equipment from the elements. In this case, the station is located inside a Communications Shelter, otherwise known as a Comm Shell
We service & Sell Sinclair RF products, including duplexers, combiners, antennas and custom test equipment.
We custom tune many different types of duplexers, both in our Canadian lab, as well as onsite, anywhere in the world...literally.
Whether your site is located on a mountain in the Andes, or in Colorado, we provide custom services to meet your needs.
