Common-mode currents are detrimental to antenna system efficiency, noise or unwanted signal ingress, and/or pattern. Common mode currents:

  • in verticals with sparse counterpoise systems negatively impact system efficiency
  • in all transmitting antennas can increase local RFI
  • in receiving systems increase noise floor
  • in all antenna systems can alter antenna pattern, especially in nulls
