by Chris Woodford. Last updated: July 22, 2021. Sound—energy we can hear—travels only so far before it soaks away into the world around us. Until electrical microphones were invented in the late 19th century, there was no satisfactory way to send sounds to other places. You could shout, but that carried your words only a little further. You couldn’t shout in New…
Q. What factors should I take into account when purchasing an antenna? A.

The part of a transmitting or receiving system which is designed to radiate or to receive electromagnetic waves”. An antenna can also be viewed as a transitional structure (transducer) between free-space and a transmission line (such as a coaxial line). An important property of an antenna is the ability to focus and shape the radiated…
An overview of the different areas of the radio spectrum the types of radio transmissions or broadcasts that they contain Radio waves are one form of electromagnetic radiation. They have the lowest frequency, and hence the longest wavelengths. Above the radio spectrum, other forms of radiation can be found. These include infra red radiation, light,…
An approach to upgrading The Foundation Licence, as an entry-point to amateur radio, is providing experience with hobby communications and the opportunity for further hands-on learning.

If you have not already done a practical assessment under either a Foundation or Standard licence or have the Standard Licence Regulations Exam, you will need to do them too.…
Ultra High Frequency (UHF) is a electromagnetic radiation. Especially its frequency is between 300 MHz and 3 GHz (3,000 MHz). Because of short wavelength, UHF has strong directivity and it has small area. UHF is commonly used for television signals. It is strong enough to be protected from other signal, but because of its strong directivity, receiving error by an obstacle occurs more. Hence it…
