The Uniden 800 radar detector should be able to pick up a police signal from 2 miles away, but there is never a guarantee. It also depends on the type of radar used by the police.
They can definitely pick up all types of signals. One form of the uniden 800 was used at a sheriffs office and could pick up different signals all the way from 40-50 miles away.
No. GPS signals are rather weak and the signals come from thousands of miles away. AM and FM radio stations are much stronger and much closer to humans. EMF from large powerlines and poorly grounded electronic equipment is much more likely to be harmful.
What signals? And it depends on the strength of the signal from the source
The American Indians created Smoke signals to communicate to other tribes over 750km away
The world has been broadcasting TV signals since the 1920s. That has given the earliest signals about 80 years to travel away from earth, so that means they have travelled up to 80 light years. That is about 500,000,000,000,000 miles (give or take a few million miles). That radius is enough to encompass up to 100 stars so the signals will have passed quite a few planets so far. By the time the signals reach these planets, the signals are probably far too weak to be detected above the radio noise of the universe so it is unlikely that any other life forms are watching our television programs from decades ago
about 228 million miles about 228 million miles away
It is about 93,000,000 miles away
Scotland is a country with an area of over 30,000 square miles therefore it is difficult to answer this question - see below. Gretna is 314 miles away. Edinburgh is 379 miles away. Inverness is 558 miles away. Stornoway is 693 miles away. Kirkwall is 697 miles away. Yell is 859 miles away.
Because it is not 93 miles away from us but it is about 93,000,000 miles away from us.
University of Phoenix Stadium is 278 miles away Qualcomm Stadium is 322 miles away Oracle Stadium is 547 Miles away Candlestick Park is 568 miles away Invesco Field is 728 Miles Away
The ship that was closest to the Titanic was the S.S California. It did not respond to the Titanic distress signals because the wireless operator was asleep. The Capathia did respond but it was four hours away traveling at 17.5 knots.
