What cause that white grain on tv screen?

tv reception is not clear


Answers:    Well the White grains are cause by The TVs MIXER circuit....

It Mixes the High Frequency RF signal that you get from the TV station beside an Oscillator frequency that is merely 4 1/2 Megahertz (cycles per second) Higher than the channel frequency....

Well that OSCILLATOR is in truth the source of that Snow and noise....
To OVERCOME it....You involve an RF signal that is STRONGER than the Oscillator signal.....

A really powerful antenna approaching an 8 Bay Bowtie antenna and a NICE 15 to 20 db (decibel) power amplifier for your RF signal will make reception pretty apt for a 40 mile reception area....

Put it up on a 40 foot flagstaff and you should get Up to 80 or 100 miles....
