Our home antenna is malfunctioning. Luckily there is an antenna repair service shop nearby our place.  Since we did not buy our antenna in their shop we are worried that they will not be able to help us. Surprisingly, they make calibration and test to check if they can repair our antenna to the original factory design.  We provided them the brand name, model number and other significant details like the type of waveguide transitions.

After some few test, they said they can fix our antenna and the components that they need in order to repair it are available in their shop. They have the double ridge waveguide transitions that suits for our antenna model. After some few days our antenna is properly working now! They are really good. I can’t believe that a simple antenna requires so many physics knowledge. I know that waves our important in our day to day life but I’ve never realized that many of us take for granted the importance of this. I just hope we became more aware of what waves can do in our lives so that we will be able to help improve this technology.
