Suitable for larger size vessels. Polyethylene case. The EM305 PE model has been successfully tested by QinetiQ to ISO 8729-1999, RORC and ORC and meets sections A.1/1.33 and A.1/4.39 of annex A1 of Marine Directive 98/95/EC.

Following a year of sea trials the US Navy SubPac Division Hawaii have chosen the EM305 for enhanced visibility upon surfacing for their fleet of nuclear submarines. We designed a new polyethylene case with peak performance of 62.9m² at an average of +1-3° at 10m² suitable for free suspension. Being 21.6% more effective than the glass fibre model.

Following tests and interests from the French Navy, recent tests have been carried out by QinetiQ for response to the Nato frequencies 8 - 18 GHz (I and J band) see below.
