SIGNAL BOOSTER ENGINEERING:
COMMON COAXIAL CABLE LOSS APPROXIMATION CHART

The following information is based on specifications published in recent manufacturers specification sheets that are distributed publicly and subject to change without notice.

Notations: "CC" = Corrugated Copper cable. "TA" = Trilogy Communications cable.
"STD" = Standard, non-radiating type. "RAD" = Radiating ("Leaky") type cable.

Loss is stated in dB/100 (decibels per 100 feet of cable).
"RAD Cpl" = Radiating Cable "Coupling Loss" in dB, 20 feet from cable.(nominal)
