Radio frequency bands spread in the range between 30 kHz and 300 GHz. Numerous applications exist for this diapason of electromagnetic spectrum.
A5. The Cover Range depends on 4 factors:1. Power from Transmitter; 2. Height of Antenna; 3. Gain from Antenna; 4. Around Environment.Then we can know the cover range of your station.Q6. Is the Frequency Adjustable?A6. FM Radio Band Frequency is 87~108MHz, TV Band F...

medium and long . In general "Short" range communication refers to VHF and the radios of such contact is 30-40 miles. The main use is Telephony "Medium" range communication can refer to MF Telegraphy in the 40-5535 kHz or MF Telephony in the frequency band 1,605-4,000 kHz 无线电通讯...
1.jan.1977 : more CB channels added - there had been plans for 99 channels up to 27.995 but it was decided not to allow a span of more than 440kHz - to prevent intermod breakthrough to any 455kHz receiver Intermediate Frequency stages. The business band lost 27.23 to 27.41 to CB, ...
Experimental possibilities are considered for the detection of the long range "arion" field corresponding to the massless Goldstone particles. It is shown that by using the alternating arion field in the radio frequency band one can obtain a higher sensitivity than in the case of the static arion...
