Horizontal Isolation Calculator

Enter Appropriate data (assumes use of OMNI antennas):
Frequency:  MHz (Frequency to test)
Gain1: dBd (gain of antenna1)
Gain2: dBd (gain of antenna2)
Distance: horizontal separation

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.
