A few days ago I was in need of a notch filter. So, I went to the nearby electronics shop to get one. They show me the filter they have. I am certainly not a specialist in this thing. So, I need to hire a technician to place it in the right place. I only observed that the name of the company was Channel plus, model number was not so clear but it seemed like NF-471. After placing it at the right place I choose, I seat behind my pc and have a search on this notch filter. I have found a number of good features about this at net. I am going to share it with you.

The function a notch filter performs is to block a frequency from 75 MHz to 80 MHz of CATV and 24 MHz to 29 MHz at UHF. It works over a range of frequencies from 529.25 MHz to 559.25 MHz.
At the electronic shop, the shopkeepers took it 30 dollars from me. I searched the price of notch filter, to sure about the price. I saw the price varies from 27 to 32 dollars. So, It satisfied me. The device might be tiny in size but, performs a good job. So, it seemed to me that, the price is satisfactory.
