what frequency is the cb band in america and do they use UHF?

not sure-- http://en.wikipedia.org/wiki/CB_radio http://www.roity.com/rc/cbradio/worldcb.html http://www.cbtricks.com/members/kd6tas/cbfaq5.htm Citizens' Band radio (CB) is, in the United States, a system of short distance radio communication between individuals on a selection of 40 channels within the single 27 MHz (11 meter)

You can set the band of your radio to SW or short wave. Start tuning. You will get many international channels. The clarity will be poor though. Satellite radio is the best.

Depends on what band you want to emulate. Open spectrum can be done simply using an access point. K-Band, Kr-Band, Sat systems etc... require specialized frequency generators as well as waveguides to support them.

That's a big subject.  Analog or digital? U.S., Europe, Japan, Germany, Scandanavia, Germany, UK?  All use different systems.  Most use some form of spread spectrum technology, which makes them resistant to jamming.  A good reference is Peterson, Ziemer, and Borth, "Introduction to Spread Spectrum Communications", ISBN 0-02-431623-7.\n\nAlso, see http://en.wikipedia.org/wiki/Cell_phone_jammer\n\n\nFor U.S., "The FCC has fielded enough queries about the legality of cell phone jammers that it issued a notice last year. In it, the agency warns that jammers violate federal laws that broadly prohibit interfering with licensed radio spectrum. Owning, manufacturing, marketing, offering for sale or operating a cell phone jammer is punishable by an $11,000 fine and up to a year in prison for each offense, the notice states."\n\nFrom http://www.newhousenews.com/archive/story1a092200.html

Well in some cases yes, in others, no. In the USA the three main Ka frequencies are 33.8(MPH industries) 34.7(Stalker Radar) and 35.5(Talon and Dectuar radar). And some of these guns are used in some other countries as well. In some europe countries they use Ku-band(13.400 GHz ± 25 MHz) radar guns which some american radar detectors detect\n\nIn many areas besides the US there are fixed cameras used which use 34.3 MHz which is extremely hard to detecto unless a radar detector is tuned into that frequencies. That is why you might not be able to use an american bought radar detector in another country. However there are some that that you can purchase to use every where, like the BEL 990 internation, BEL v995 international, BEL rx65 (in international mode), BEL 975r, or Valentine 1\n\nI found one website that might help you understand the different frequencies used for radar.\nhttp://copradar.com/preview/xappA/xappA.html

Radio frequency, or RF, refers to that portion of the electromagnetic spectrum in which electromagnetic waves can be generated by alternating current fed to an antenna

Find or build a jammer for frequencys above 820 and below 900mhz. Set the jammer to where the calls are made. Have a antenna wire run throughout the area. Good luck.

a Scanner\n\nMost can be programmed for a several different frequencies which you then scan. Or you can set it for scan all frequencies between two.\n\nThe Federal govt. FCC has dictated frequency bands for certain functions. Scanners cover the non-broadcast radio bands between 30 and 950 MHz.

It is impossible to give the simple answer for which you seem to be searching.\n\nThere are many frequencies which could be used to cover that distance.\n\nI recommend you read about radio communication in general and about h.f., v.h.f. and u.h.f. communications in particular.

idk, but we have 102.1 the edge in dallas/fort worth\nsweeeeeet maynnn!

Amplifiers are illegal on CB.

It just is.  Many countries use 50 hertz.  It is one of the standard frequencies.   The US uses 60.

High frequency radio waves. Around 1700 Mhz.

Spectrum is a problem in india but from my memory and you mite need to consider unlicensed spectrum and use mltpile cell site to overcome interferance issues (2/3-2/5GHz or 5.7Ghz - 5.8Ghz) as 2.7-2.9Ghz is used by Tulip and bharti uses 3.5Ghz

wireless application protocols (WAP), 3g, gprs etc... mostly using gigahertz frequencies under environmental health spectrum, around 3.5GHz.... these spectrum also covers radio waves and microwaves, some transmitted via satelites.

check google\nor yahoo\n\nand type in the name of the radio station and where you live (State only)

It all depends on what "one" is trying to pickup as far as satellite communication goes.  \nFor directv and dishnetwork the 101, 110, 119 degree satellites are transmitted on the ku band with a circular polarization at high power that is why they can be picked up with smaller dishes.  \n\nSome linear Ku band satellites can be picked up with about a 30''to 36'' dish depending on where you live and what you would like to pick up.\n\nMost cband needs at least 6ft. dish preferably 10ft. dish to pick up. If you have a cband dish depending on the size of the mesh you can use it to pick up linear ku band.\n\nWithin the last two months I helped install 2 14 ft. solid aluminum dishes that were used to pick up horse races and they do not want any downtime so the bigger the better.\n\nSo I would say yes one could come across a situation where they need a dish bigger than 1 meter.
