Complete all white boxes and then click any calculate button to obtain results in the green boxes.
If you are not using dish antennas at one of both ends, then estimate the gain in dBi of the dipole, tin can, horn etc that you have. e.g dipole gain = 3 dBi, tin can 7 dBi, bi-quad 8 dBi, helix 12 dBi etc.
Input numbers into the box for antenna diameter and keep altering the number till the antenna gain is as you want it.
I would be interested for anyone to evaluate this calculator and put right any errors, make suggestions for improvements etc.
