The ES-110 generates a stable source of 10 MHz using GPS (Global Positioning System) satellites as a reference. If frequency distribution is needed, we offer the ES-210, a Quad 1x6 1/5/10 MHz Distribution Amplifier. The ES-210 provides four independent 1x6 Frequency DAs in a single rack-mount enclosure. The ES-410 is a four output version of the ES-110. The ES-410 was introduced and won Radio Magazine's Best of Show Award at the 2016 NAB Show.
