All these above problems actually come under the purview of reception related issues.
By the term 'television reception' we mean how well your television is able to broadcast the transmitted signals. Suppose, if you are residing next to the broadcasting station, then you will be able to receive better reception. This will happen all because of the reason that there will be no barrier which will be hindering the way of the transmitted signal captured by your television antennas system.
On the other hand, the farther you will be from the transmitting tower, the more is the possibilities to receive fuzzy and distorted signals. Emerging tall buildings, trees, distance from the broadcasting station, and some other factors interfere with the transmission signals. There are some ways through which you can improve the reception of your installed antenna.
