In the case of a single bay Nicom BKG-77 configuration, it’s essential to note that it operates with a gain of -3 dB, effectively causing a loss. To illustrate this further, let’s consider a scenario where your feedline exhibits a loss of 0.8 dB per 100 feet, and the lightning arrestor contributes a 0.1 dB loss. With 150 feet of LMR-600 cable, you’ll encounter a 1.2 dB loss from the cable alone, and when factoring in the lightning arrestor, the total loss amounts to 1.3 dB.
