Radio Mobile - RF propagation simulation software

dBiC is decibel above the gain of a isotrope antenna as a reference where the isotrope antenna has the same circular polarisation as the antenna of which the gain is expressed.

The isotrope antenna is a mathematical antenna with a radiation pattern of a perfect sphere.
From this background it is calculated that a dipole antenna has a gain of 2.15 dB referenced to the isotrope antenna. template modified by PE1MEW
