The higher the TV antenna, the better?

The reception of television images, mainly depends on the television signal radiation to the reception point of the electromagnetic field strength of the size, and the height of the antenna is not absolutely proportional to the relationship. The best point for TV signal reception occurs at intervals in the direction perpendicular to the ground. Therefore, before installing the antenna, it should be debugged at different heights and directions, compare the effect of reception, choose the best location, and then determine the height of the antenna, rather than the higher the effect of the higher the better.
