Mounting options
Sailing Yachts – Halyard Mount
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.
IMPORTANT
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°
Utilising Echomax stainless steel mast brackets (available separately) fit the 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
