There are two types of frequencies: VHF and UHF. VHF is the most suitable for businesses that must communicate across long distances . UHFprovides high yet short wavelengths, best for communicating within smaller spaces and metallic buildings.

The 7000 kHz (7 MHz or 40 metre) band is useful for daytime communication up to a distance of 800 km via E and F layers. Long distance world-wide communication takes place in this band through F2 layer.
Read moreWhat is medium frequency?
Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz) . … The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometer (1000 to 100 m).
Read moreDo weather radars use radio waves?
RADAR stands for RAdio Detecting And Ranging and as indicated by the name, it is based on the use of radio waves . Radars send out electromagnetic waves similar to wireless computer networks and mobile phones.
Read moreWhat wavelength is weather radar?
The National Weather Service (NWS) uses S band radars on a wavelength of just over 10 cm . The drawback to this band of radar is that it requires a large antenna dish and a large motor to power it. It is not uncommon for a S band dish to exceed 25 feet in size.
Read moreWhat is S band Good For?
The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites , especially those used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz.
Read moreWhat is C-band in radar?
What is C band radar? C band radar uses microwave frequencies ranging from 4.0 to 8.0 (GHz) . The C band is used for many satellite communications transmissions, some Wi-Fi devices and cordless telephones as well as some surveillance and weather radar systems.
