" A Non – Directional radio Beacon (NDB) is in principle a simple radio transmitter which radiates a signal equally in every direction (hence 'non-directional')...

2006 (UTC) I am suspicious that these "Letter Beacons" may actually be the non-directional navigation beacons used by aircraft and ships. Many of the NDBs...

the airport. Something 20km away is not relevant. The El Turbio non-directional beacon (Ident: BIO) is located on the field. See problem number two. And...

by events - Ice pool deleted on notability grounds. Individual non-directional beacons are not notable. There's at least one other Alaska-related usage...

IDL for Idlewild– now JFK, and EWR for Newark. The Sarasota NDB (non-directional beacon) was the only radio navigational facility between Tampa and Ft....

The nearest radio navigation aid for pilots is the Wollongong Non-Directional Beacon installation located within the airport boundary. All airline flights...

fly opposite the needle indication. Log periodic antennas are highly directional and do not provide a sufficient signal to support a backcourse. In the...

Ultrakurzwellen-Landefunkfeuer" is not quite right. There are no highly directional antennas as described. For a brief and right description look at [[1]]...

called an infraparticle. The existence of the directional charges is related to soft photons. The directional charge at t = − ∞ {\displaystyle t=-\infty...

the carrier output, along with the reference signal (which is omni-directional, non-rotating and equal amplitude in all directions). The electronically...

19:45, 18 July 2009 (UTC) The article says the receiver antennas are directional, but what exactly does that mean? If the user gets a bearing on a transmitter...

think what. When it refers to Radio beacons is it saying that the minimum required is an Non-directional beacon? CambridgeBayWeather (Talk) 23:37, 5...

impact ATC asked the pilot to make a 360 deg turn over Varamin Non-directional Radio Beacon (NDB). The pilot made this 17nm to the north without advising...

accomodate letter beacons? Article size seems not an issue. Numbers station is currently 24K, and Letter beacon is only 1.5k. How would Letter beacon be helped...

determing which bearing a radio signal is coming from only requires a directional antenna. So it would not be hard for a single ship to move in the direction...

"The effect can be visualized in terms of a number of highly directional sound beacons, all of which the vibrato causes to undulate back and forth in...

(UTC) You would only have a problem during bank if you had a very sharp (directional) beam. If the beam is wider, some part that goes, wlog, to the left as...
