The Aperture unit is a one of a kind item, designed to expand the range of any pre-existing multi axis lens control system. The unique design expands the range from the RX side of the transmission, so it can be added to any system without any additions to the TX side of your units. There are countless orientations for this unit, but it requires a hand unit with an SMA antenna port for base operation. This is a single antenna unit, and requires additional accessories to make a complete turn key package. please see Aperture Unit Package (1x) for a turn key package.
