TVRO S4 (45cm)


A light marine satellite TV antenna for the open calm seas

The EPAK® S4 is a light-weighted and small marine TV antenna (only 12 kg and 45 cm dish diameter) designed to work properly in open calm seas, thanks to a tracking speed higher than the R-Series'one.

Optionally equipped with a Twin LNB, which allows you to connect two independently receivers, our compact marine TV antenna is able to memorize up to 20 different satellite frequencies.
