70-centimeter band. I don’t know if that makes sense. It’s basically used for a unified idea. For instance, I am 41 years old, so I am a 41-year-old man. The same logic applies there too. If what you are describing is part of the whole description, the dash seems to be used, whereas if what are describing doesn’t inherently cObtain that description, it can be by itself, and plural. I don’t think I’m describing they’ll why all that well, so if you have questions, please ask. I guess it boils down to we are talking about one band versus actually measuring the wave, if that makes sense.

you have a 5 dB improvement between radios at 450 MHz vs 144 MHz in real life. What about receiver noise figure, transmit power, ambient noise level, propagation, etc.? (In particular, lower frequencies are probably better in a hills and valleys situation.) Has someone published a test that shows 70 cm repeaters truly have much greater range than 2 M machines or is this a theoretical speculation? This kind of claim must have a reliable reference, or it should be removed.--

actually are, how much the band is used, examples of how it remaining an amateur band is in the public interest.... I think this article lost focus on the fact that
Knowledge is intended for a general audience, not a place to conduct hobbies. Your grandmother doesn't know or care what a continuously loaded coil spring antenna is.
679:
The present "Comparison of the 2-meter and 70-centimeter bands" is somewhat debatable and totally unreferenced. It is true that for a given physical size, an antenna for a shorter wavelength can have more gain. (But note that collecting area scales as wavelength squared! :-) This does not show that
700:
In many areas of the US, at least, an important difference between 2m and 70cm is that the 2m repeater slots are all allocated (though the band is pretty quiet, on average) while repeater pairs on 70cm are still available. The difference in propagation (weak signal, long distance) is pronounced,
778:
The 70 cm band is being targeted as one of the places for the FCC to collect 500 Mhz of poorly used spectrum to auction off for wireless broadband in the United States. Since the ARRL is surely going to fight that, it might be useful to find information about how many licensed repeaters there
1090:
Hi! Thanks for asking! The distinction of the dash connects the number to the band as one single thing. You would write “70 centimeters” if you were measuring something, and the plural is used, whereas “70-centimeter band” is just one whole thing. The wave is 70 centimeters, so it is the
753:
So while we now have info about australia and the UK, it would be nice to have things from other places. More specifically, the ITU regions 1/2/3 regulations would be sufficient, I think, to remove the banner. Oddly enough, the band plans I could find from ITU-2 are only for MF/HF:
655:
I've only recently started looking into
Amateur radio and I have a question about the 70 cm band: What are the characteristics of this band that would make using it preferred to two meter? If someone can help, please improve the 70 cm article.

which is weird to me. I haven't put that banner in there, so I am hesitant in removing it (being in Canada), but I feel there's already good information about things outside the US in there.. not sure we need that banner, basically. --
612:"70 centimeters is the most popular UHF ham band " while probably true, reads in a way that makes it subject to misinterpretation. If you read quickly, as I did, and miss the "UHF" bit, one sort of takes a double-take.
