What do you need to know about a repeater?
To use a repeater, you must have a transceiver that can transmit on the repeater’s input frequency and receive on the repeater’s output frequency. The input and output frequencies are separated by a predetermined amount that is different for each band. This separation is called the offset.
Is it possible to connect another repeater to an existing router?
You can connect one repeater to another one. But the performance would be worse, so do not expect it to perform like it would with just the router because of the overhead involved while repeating the signal. Consider shifting your router to the optimum position instead of using too many repeaters.
Can a handheld radio link to a repeater?
Since the remote base transmitter is keyed off and on, its duty cycle is really no more than the user so you don’t have to be overly concerned about it burning up because of not being rated for continuous duty. Many times a handheld radio (like the Icom IC-3-AT) on low power is plenty good enough to link to another repeater.
What’s the best link frequency for a repeater?
However you do your point-to-point linking, remember to coordinate your link frequencies with the local coordiators. Many areas use frequencies in the 420-440 range for links, but in some areas these frequencies are not available. In Ohio, for example, links are between 433-434MHz, and 445-447MHz due to the “Line A” situation.
A basic repeater consists of several individual pieces that, when connected, form a functional system. Here’s a simple block diagram of a repeater: Most repeaters likely use one antenna. The antenna serves both the transmit and receive RF (Radio Frequency) signals that are going in to and out of the repeater.
What makes a duplex repeater a repeater?
A duplex repeater, in concept, is not really a complicated device. It’s a ‘duplexed’ two-way radio set that listens on one frequency, then re-transmits what it hears on another; and does it simultaneously.
Do you need an offset for a repeater?
Most repeater installations use the same antenna for transmit and receive. Without having an offset of 600 kHz the repeater would simply hear itself when it was transmitting on the same frequency it was listening on. Even with the offset, the two frequencies are close enough that some isolation is required.
Where is the antenna located on a repeater?
The antenna serves both the transmit and receive RF (Radio Frequency) signals that are going in to and out of the repeater. It’s generally a high performance, durable, and rather efficient antenna located as high on a tower or structure as we can get it.
