Tappers (asymmetric splitters)

A tapper (asymmetric power splitter) takes a small, precisely defined share of the trunk-line power to an antenna branch and passes the rest on with low through-loss. Asymmetric splitting is the standard answer for long trunk lines: each antenna along the line takes only the power it needs.

With tappers, the antennas along a long corridor, through a car park or up a tall building end up at the same power level without draining the trunk at its start. Antennas near the start of the line get a high coupling value, antennas near the end a low one.

BDC tappers cover 380–3800 MHz and handle 300 W average power. There are nine coupling values from 4.8 dB to 30 dB, shown in the model name; through-loss per model is in the comparison table. Return loss is ≥ 21 dB and PIM ≤ −160 dBc on every model as guaranteed minimums, with 4.3-10 female connectors.
