Antenna Horizontal Isolation Calculator

The calculator provides an estimate of the isolation provided by two horizontally separated antennas. The data entered will assume use of OMNI antennas.

Frequency to Test(MHz)

Distance of horizontal separation

Gain of Antenna 1(dBd)

Gain of Antenna 2(dBd)

Note: Data is based on the use of half-wave dipole antennas. The data also provides acceptable results for gain type antennas if the spacing between the gain antennas is at least 50 ft. (15.24m) (approximately the far field). Experience has shown that isolation improves when the two horizontal spaced antennas are in the near field of each other.
