What is it about the design of an antenna that helps it to function more efficiently? How exactly does it pull the signals in?
Would it hurt, help, or not really affect the reception, if I attatched a metal object to it? Would it give it more surface area for signals to be absorbed through or interfere with the origional design?
How does the design of a TV tower antenna help it to get a better signal?
The number and size of the elements (rods) are determined by the frequency you want to receive. To receive multiple frequencies, the rods will be of different lengths. The should be horizontal because TV signals are horizontally polarized.
The design is important and any added metal, etc., would probably do more harm than good as it would interfere with the design.
I put in the link below to give you pictures of the antennas. Each design has its own advantages and disadvantages, depending on what you need.
