The propagation of radio waves in an enclosed space is very different from their propagation in an open space. The interference of the magnetic field in the room is more pronounced. Therefore, setting up an indoor antenna is a laborious and troublesome process. When installing and configuring indoor antennas, you will have to fulfill several necessary requirements and make certain manipulations.
Instructions
Step 1
Install the indoor antenna close to the TV (or directly on top of its cabinet). It is advisable to locate the antenna near a window or balcony. This is especially important if the windows face the repeater tower.
Step 2
Move the antenna around the room to find the optimal location where the TV will display the best picture. Carry the antenna slowly, observing the change in image quality both horizontally and up and down. Memorize or write down where in the room and in which antenna position the image quality was best. Gradually extend the antenna "mustache" (telescopic MV vibrators) to a length at which a good image is obtained on the "meter" channels. In some cases, the length of the "whiskers" may be different. Also select the optimal angle of divergence between the "whiskers", while achieving the best image quality.
Step 3
Move the entire body of the antenna to tune the UHF channels in the horizontal plane until a good image appears on the TV screen. If the indoor antenna has a gain control, adjust the position of the control for the best picture quality. Change the position of the antenna in space when switching from one channel to another, if necessary for additional adjustment of the image quality, and also adjust the position of the "whiskers", their exit and the angle between them. Adjust the gain control if necessary. Of course, this is not very convenient, but you have to come to terms with it. Do not forget to plug in the power supply for active antennas. At the same time, the LED on its body should light up.
