In 2006, Etherstack joined with Aeroflex to develop and market products for performing conformance tests against the TIA P25 protocol.
The company expanded and modernized in the early 1990s, with three new plants including one in Iloilo, part of a P25 billion investment plan.
The company manufactures antennas to suit all frequencies from 150 MHz to 5 GHz, covering a wide range of applications including 3G, DAB, GPRS, GPS, in-building, ISM Band, M2M, GSM, P25, PMR, TETRA UHF, TETRA 800 and LAN.
Rudd was involved in the development of the V16 and four-cylinder P25 cars and started to assume more prominence after the Rubery-Owen takeover of the team.
