*Each entry is the maximum cable length in feet which will yield a feeder loss of 1.5 dB or less over each frequency band.  A power efficiency of 71% is realized at an attenuation level of 1.5 dB.  A larger cable will improve power efficiency.  For example, a power efficiency of 80%, which corresponds to a feeder loss of 1 dB, will be realized by multiplying any cable length in the table by 0.67.
