Does FM or AM travel further?
FM transmission has broadcast waves ( 88-108 MHZ) that are shorter than AM broadcast waves (540 – 1600 kHz) and do not go as far. FM radio waves also travel horizontally and skyward. However, due to the higher frequency of the carrier waves, the waves that go skyward are not reflected.
Why does a two way radio have a limited range?
Under these normal conditions, the range of the radio will be limited because of obstructions, such as trees, hills, or buildings. These obstructions block the signal and dramatically reduce the range of a two-way radio. So what type of range can you expect from your radio?
How many miles can a 2 watt radio go?
Usually half a mile up to two miles, depending upon your terrain and the power of your radio. In the same environment, a 2 watt radio with a long antenna would provide considerably more range than a half watt radio with a short antenna.
How does HF radio communication between two points depend on?
HF radio communications between two points that are separated by more than about 15 to 25 miles depend almost solely on propagation of radio signals through the ionosphere. The ionosphere is a region of the Earth’s upper atmosphere that is ionized primarily by ultraviolet rays from the Sun.
What’s the maximum distance a radio wave can travel?
Page 4 If the radio wave leaves the earth at an elevation angle of zero degrees, just toward the horizon (or just tangent to the earth’s surface), the maximum distance that may be reached under usual ionospheric conditions is approximately 2,500 miles (4,000 kilometers).
Can you get good radio reception in a bad location?
You can get the same reception in a bad location (using a great antenna) as you can in a good location (using a bad antenna)! But lets work on improving both! Statement from Radio Bob: You MUST have an antenna (of some kind) to receive any signals on a radio!
How many miles away can I get an FM radio?
If you have all three of these, you could potentially receive an FM station up to 100 miles away! However, most of us have, at best, only one of these items…
What should I do if my radio signal keeps dropping?
Try twisting the antenna while listening to a station. If the signal keeps dropping and coming back in, tighten the antenna and get the wire connections fixed.
Why is my car radio reception so weak?
>>> Read more: Car antennas 101: There are more that you need to know! Most of the time, the main problem of a weak car radio reception is the bad antenna. In some cases, the connection between the car radio and antenna gets damaged by rust or any other similar factors. It happens gradually over time.
