Suitable for small yachts and motor vessels 6 to 7 metres in length.
It is 360mm tall and 197mm wide, weighing just 1.2Kgs. with fixing centres at 305mm.
The EM180 has a documented maximum radar cross section of 8M2 and is suitable for vessels up to 7-8 metres. We have utilised the largest possible patented symmetrical stacked array with the smallest possible robust Polyethylene case with minimum windage and weight. The EM180 is suitable for deck, mast mount fixing, or halyard suspension and is available in white, orange or yellow. Used extensively on marine buoys and for tsunami warning buoys.
Height: 478mm (overall)

Echomax reflectors use a symmetrical arrangement of interacting corners. Whilst its centreband response pattern is maintained at 15° tilt RCS is -5dB. To counter this, and avoid 'mast shadow'.
Pass a bight over the yardarm via a dead eye. Return bight through reflectors eye and secure taking lines through bight. Take tails through reflectors bottom eye and then to separate cleats via loops at --xx--.
Yachtsmen will be aware of the need to trim the reflector when on the reverse tack, failure to do so will result in compounding the angle of heel rendering the reflector inefficient.
Note: Reflector trimmed to leeward 15°. Mast heeling to 30°
Echomax may be fitted in any position around the mast (i.e fore or aft).
Hypothetical figures on mast shadow may be viewed .
Utilising Echomax stainless steel mast brackets fit reflector as high as possible on the mast, using Monel or stainless steel rivets (3/16 x 1/2" 4.8 x 12.7mm). To avoid electrolytic action use zinc chromate paste between bracket and mast or closed cell foam tape. Firstly fix top bracket to mast in the required position, measure distance vertically between centres, mark position of lower bracket then drill and fix. Use two stainless steel hexagonal bolts 8mm dia x 30mm long to fix Echomax to the mounting brackets
There is also a deck bracket available for mounting to a flat surface.
