If the [[beam divergence]] of a transmitter is small, i.e. it forms a tighter cone, then more power actually reaches the receiver. However, low divergence means that the beam must be very well aligned for the spot to actually coincide with the receiver aperture. By contrast, if the transmit beam is wider, the spot becomes larger and it is easier to hit the receiver, but less power will be transmitted into the receiver system. This tradeoff is an ongoing high-level design question for SSI's [[OpComms]] team.
