A holotransmitter was a device for long-range communications and transmissions. During the Age of the Empire, the rebel cell Spectres' starship Ghost was equipped with a holotransmitter which they used to beam a propaganda broadcast to the Imperial Communications Center on Lothal in 4 BBY. During the time of the New Republic, it was used to transmit the Five Sabers competition.
