How far can a repeater?
Repeaters within signal range of each other cannot transmit on the same frequency and PL tone without causing interference. Repeater range is roughly 25 miles. Areas of higher network usage require more repeaters than areas of less network usage in order to provide coverage for all operators and minimize interference.
What is the range of a radio repeater?
Amateur repeaters in the 144–148 MHz band usually use a 600 kHz (0.6 MHz) separation, in the 1.25-meter band use a 1.6 MHz separation, in the 420–450 MHz band use a 5 MHz separation, and in the 902–928 MHz band use a 25 MHz separation.
HOW FAR CAN 2 meter radio reach?
about 25 miles
On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is about 25 miles (40 km). Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).
What is repeater spacing?
Whereas analog signal amplifiers are spaced at 18,000 meter intervals, digital signal repeaters are typically placed at 2,000 to 6,000 meter intervals.
How far can you transmit with 50 watts?
They assume a 5 watt handheld, 50 watt mobile, 5/8 wave mobile antenna with 6 dB gain and 5/8 wave, 6dB gain omnidirectional base antenna at 50′. Urban Environment – Around 1/2 – 1 mile from handheld to handheld, up to 2 miles mobile to handheld, and up to 5 miles or more, base to mobile, with base antenna at 50′.
Where should repeaters be placed?
Typically, you want to place the extender mid-way between your router and where your wireless coverage starts to drop.
What are the types of repeaters?
There are several different types of repeaters; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in an optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal.
What is the offset for a 2 meter repeater?
-600 kHz
On the 2m band suppose a repeater has an input frequency of 146.250 MHz and an output frequency of 146.850 MHz. The offset is 146.250 – 146.850 = -0.6 MHz, or -600 kHz. This is a negative standard offset.
Do you need tone to listen to a repeater?
Tone – For most repeaters, you will need to transmit a CTCSS tone to access the repeater. (CTCSS is Continuous Tone Coded Squelch System.) Repeaters with carrier access do not require a tone, so you can skip this step.
