AQUA 20/20 Recommendations
The audio cable for the AQUA 808 transmitter also serves as an antenna. The length of cable is cut according to the
specific frequency range. Do not alter the physical length or coil the cable in use. Doing so will affect the antenna
efficiency of the transmitter, and reduces operating range.
