![]() Most radio repeaters offer real-time transmission of messages, taking only 50 or so milliseconds to process and resend a signal. As a result, the radio transmits on the repeater’s input frequency and reverts to the repeater’s output frequency when the radio is not used for transmitting. In order to use a repeater system you will need to connect your radio so that it is set to transmit the repeater’s output frequency as well as enable the radio’s offset mode. One frequency transmits the message and the other receives it. Repeaters are built using two different frequencies that seamlessly come together. ![]() If you live in a region surrounded by high mountains or tall buildings a repeater is incredibly useful. Emergency personal, police departments, commercial businesses and ambulance services all use repeaters to ensure important messages are transmitted and received. A repeater system is located at a higher elevation, this device receives and re-transmits signals using a higher power so that it will reach its intended destination. This increases the overall range of your two-way radio.Įven with superior conditions most two-way radios only reach so far in distance before a repeater is needed. Simply put, a radio repeater takes a poor, weak or ineffective radio signal and amplifies it as well as rebroadcasts it. Instead, extending and improving your antenna is often the easiest way to improve radio range. You don’t have to run to the top of the closest hill to restore two-way radio communication. This is why if you stand at the top of a mountain you are going to get the best signal strength, there’s nothing in your way because you are at the highest point. The higher your radio antenna the less likely it is going to encounter interruptions as it travels from one radio to another. This is why many go with external antennas mounted to the roof of the vehicle. Simply mounting a two-way radio inside of a vehicle can create interference issues. Two-way radio signals travel in a straight line meaning mountains, buildings, trees or even a group of people can get in the way of transmission signals. Radio Antenna BoosterĪ radio’s signal strength relies on a number of factors including the radio antenna size, the frequency band, and surrounding landscape, including if you are indoors or outdoors. Not only do radio antenna boosters and extenders increase the range you have to communicate, but also they provide clearer voice quality for ease of communication. Radio range can be increased through an extender, repeater or booster. A radio antenna booster, or a signal booster of any kind, will help extend your two-way radio range. Good luck, I'm a 40 year Ham Radio Operator with Search & Rescue.Two-way radios have a specific range they operate within and anything outside of that will cause your radio to lose signal. But most likely the Ferrite Coils (snap on beads) on your LED power wires next to the light will do the trick, since you did not have this problem before the LED light installation. RF signals can also be generated through the engine electronics. While you are at it you should install a line filter on your radio power wire. ![]() You can buy these on Amazon, they are cheap. ![]() However you can install them on your power wire (as close as possible) to your LED light. If your LEDs are Amazon imported lights then they do not have built in Ferrite Coils. If your power wires are close to or are connected to your radio, then the LED RF is drowning out your radio. The radio frequency being transmitting through the power wire is close to the radio frequencies in your audio radio station you are trying to receive. This circuit it using the power wire as an RF radio antenna. The LEDs are diodes which require an electronic circuit to light. Your LED lights are emitting RF radio frequencies.
