What is the relationship between very high frequency (VHF) and ultra-high frequency (UHF) leakage and ingress?

The concept of leakage and ingress in the context of VHF and UHF refers to how radio frequency signals can leak out of or intrude into a cable or system. The relationship between VHF and UHF leakage and ingress is characterized by the fact that these two frequency bands operate at different wavelengths and have distinct propagation characteristics.

In practice, VHF frequencies range from 30 MHz to 300 MHz, while UHF frequencies span from 300 MHz to 3 GHz. Because these frequencies are separated by a significant bandwidth and have differing antenna characteristics, the mechanisms of leakage and ingress are not directly related. Therefore, any leakage encountered at VHF does not inherently influence or correlate with leakage at UHF, resulting in the conclusion that there is little or no relationship between them.

This understanding is essential in the context of signal integrity and system design, as it allows technicians to address issues specific to each frequency band without assuming a direct connection between them. This separation is crucial for maintaining the quality of service in communication systems that operate across these frequencies.
