We purchased ours from:
EchoMax EM230+ Radar Reflector for our mast
We ordered the EchoMax EM230+ Radar Reflector (echomax.co.uk) for our mast. Echomax would like you to hang the reflector from the spreaders but that means you need to move it when you tack. Besides we have thin spreaders so it will be a mast mount for us.
We also bought the mast mounts.
