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
