It has been a long time since I took electro-magnetics courses in university. It is time to take
a primer on Yagi antenna design. Yagi antenna are very directional but it gives you a better
signal to noise ratio and allows you to send and receive longer distances than other antenna
designs because the directionality focuses all the power in a narrow cone. As with all
antenna it is more effective if there are no obstructions between the sending
and receiving antenna. Rain and other airborne particles can also cause scattering
lessening the effective distance. Unobstructed line of sight is the rule of thumb if
you do not want to do the calculations.
Here is a good reference on how to construct Yagi antenna for a few dollars of materials.
It just requires that you measure accurately.
