Subspace antenna

From Memory Alpha, the free Star Trek reference

The subspace antenna is a component of the transceiver array, used to transmit long range communications. (ENT: "Dead Stop")

According to a log entry found aboard the Stargazer, falsified by the Ferengi, Jean-Luc Picard stated that he may have mistaken an unidentified Ferengi starship's subspace antenna for a weapons cluster. (TNG: "The Battle")
