* '''Cable (insertion) losses''' must be taken into account when using antennas with long cables. It is a measure of the amount of energy that is absorbed by transmission line (cable) as signal travels down and it is measured in decibels (dB). In general, a smaller diameter cable has more loss than larger diameter cable. For a specific cable type (different cable types have different losses), the longer the cable length the greater the amount of energy it absorbs. Also, losses depend on frequency – the higher the frequency the greater the loss. | * '''Cable (insertion) losses''' must be taken into account when using antennas with long cables.
