A Yagi-Uda directional antenna consists of a driven element (a dipole), and one or more parasitic elements -- a reflector (5% larger than the driven element) and directional elements (5% shorter than the driven element). This difference helps increases the gain and directionality of the antenna in the desired direction.
Yes, the Yagi-Uda antenna has several parasitic elements, in the form of a reflector ("behind" the driven element) and the directional elements ("in front" of the driven element).
A yogi is a directional antenna.
bandwidth is less..
As a radio antenna.
i would help you but question is not clear. on top of what south tower?

how to measure the length of elements and spacing of elements
To cut a wire or aluminium tubing length for a dipole antenna take your frequency in Megahertz that you want to tune the antenna to and divide that number by 468. This will be the full wave length of the frequency you will be tuning to. For general purpose listening cut the antenna to mid frequency of the FM band. Cut this wire (or tubing) into two equal pieces. This will be the driven element feed point. For a yagi antenna cut a reflector 10% larger that the first cut and place it 1/2 wavelength behind the driven element on the boom. For the director cut the wire length (or tubing) 10% smaller that the driven element and place it on the boom 1/2 wavelength in front of the driven element. This will give you a three element yagi antenna.
Monopole is an antenna with just the radiating element where the ground of the transmitter is connected to an electrical ground which serves as an Image ground to the radiating element. Thus the name "mono" pole. Dipole is where the ground and the radiating elements are connected to two different elements where one is the radiating element and the other is the ground to the later. Thus the name "Di" Pole Cheers by zafran khan
Yes - reflector element and directional elements.
The tip of an antenna is commonly referred to as the "radiating element" or "antenna tip." This part is crucial for the emission and reception of electromagnetic waves. In certain types of antennas, such as dipoles, the tips are where the current is most concentrated, playing a significant role in determining the antenna's radiation pattern and efficiency.

This question cannot be answered as it gives no reference to the calculation your looking for: Frequency, Range, load, etc.
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
Polonium is a natural, radioactive, chemical element.
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
A passive antenna is an antenna that is not powered by an amplifier.
