Talk:L band

Television satellite uplink facilities typically use L-band to move signal around the plant before it is up converted to K-u, or occasionally, C band for the actual uplink. — Preceding unsigned comment added by 72.0.135.96 (talk) 19:24, 26 February 2018 (UTC)

Perhaps the NATO L-band should have its own article.--SkiDragon (talk) 00:21, 24 October 2008 (UTC)
 * Agree. These are completely different bands - the only commonality is the name. - Crosbie 08:06, 4 October 2014 (UTC)

Optical communications L band range
Here it says "L band is also used in optical communications to refer to the wavelength range 1565 nm to 1625 nm.", but in EDFA it says "the Long, or L-band, from approximately 1570 nm to 1610 nm.". Perhaps there is no clear, generally accepted definition, but there should at least be a source for the 1565 to 1625nm range. Ornilnas (talk) 06:53, 16 May 2013 (UTC)

Military Use
The current section, "In the United States and overseas territories, the L band is held by the military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC) solutions." reads like military telemetry has committed some offense against digital radio. Military telemetry far predates the digital radio applications cited, and in any case, military telemetry has not "forced" any particular kind of implementation of that technology on the people that want to use it. The phrasing implies some kind of malice or unfairness. Wolfram.Tungsten (talk) 00:39, 14 January 2014 (UTC)

Did the L band once include the terrestrial UHF 470-860Mhz band?
Or whose L band is Eimac referring to in their klystron data sheets such as 3K20000LA from 1953? 2001:8A0:5E40:DC00:3005:2968:70CB:B896 (talk) 20:55, 28 October 2020 (UTC)

"L band (template)" listed at Redirects for discussion
An editor has identified a potential problem with the redirect L band (template) and has thus listed it for discussion. This discussion will occur at until a consensus is reached, and readers of this page are welcome to contribute to the discussion. 1234qwer1234qwer4 14:13, 22 January 2023 (UTC)
