Note: Coax losses shown above are for 100 feet lengths.
Loss is a length multiplier, so a 200 ft length would have twice
the loss shown above and a 50 ft length would have half the loss.
This multiplier factor is why you should keep cable installation
lengths between radios and antennas as short as practical!
