The working distance depends a lot on the receiver that's being used to pick it up.
The Pioneer-11 spacecraft was launched in 1973. The last radio contact with it
occurred in 1995, when it was 4 billion milesfrom Earth. Communication might
have laster longer, but its on-board power source ran out of gas at that point.
The spacecraft transmitted just a few watts of radio power, at microwave
frequencies. But the antennas that were used to receive its signals are dishes
hundreds of feet across, with supercooled electronics.
What else can I help you with?
Circuit diagram of radio telegraph transmitter?
a transmitter that sends out morse code signals
Is a satellite radio antenna active or passive?
A satellite radio antenna is typically considered a passive device. It receives signals transmitted from satellites but does not amplify or generate its own signals. The antenna captures the radio waves and sends them to a receiver, which processes the signals for audio output.
What is the galaxy called that sends radio waves?
Quasars
What do radio waves bounce off?
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.
What is a Star that sends out pulses of light and radio waves in regular bursts called?
A pulsar.
Which type of modification of radio waves sends signal the farthest?
amplitude modulation
How do radio antennas get a connection?
It sends out signals through the air to a radio tower.

What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
How do wireless antennas share information?
they dont. An antenna is simply a piece of metal hooked to a device (normally a radio or a walkie-talkie). A receiver (for example, a radio) pick up electrical signals from the antenna, and a transmitter sends them to the antenna. They can be combined to form a transceiver which then sends and receives signals from the antenna.
How do radio antennas work to receive and transmit signals?
Radio antennas work by converting electrical signals into electromagnetic waves that can travel through the air. When a radio station transmits a signal, the antenna sends out electromagnetic waves. When a radio receiver picks up these waves, the antenna converts them back into electrical signals that can be processed and heard as sound. This process allows for the transmission and reception of radio signals over long distances.
What does a wifi antenna do?
It sends and receives radio signals to and from other wireless devices. Similar to a CB radio only in computer language.
What sends a radio frequency to a robot?
A transmitter sends a radio frequency to a robot.
What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
Is electricity needed ta make an external antenna work?
No, an external antenna can work without electricity. It simply picks up radio frequency signals from the air and sends them to the device it is connected to. The device, such as a TV or radio, uses its own power to process and display the signals.
What is antenna role in space communication?
it receives signals and sends out signals
How did the early radio differ from the early telegraph?
The Telegraph Required Wires The Radio Did Not
