the radar antenna is a good sized metal construction. It will reflect. Also, since it is tuned to the same (about) frequencies, it can passively re-radiate some of the signal.

Other boats might have something like the CARD system aboard to pick up other vessels’ radar: http://nordkyndesign.com/collision-avoidance-at-sea-ais-alarm-project/ But those systems haven’t been available new for a decade. The other type of device that you could have on your vessel to help other radar-equipped vessels see you better would be an active radar target augmentation system like the Echo-Max: https://www.echomax.co.uk/radar-target-enhancers-x-band-dual-band.html Or a Search and Rescue Transponder (SART): http://www.offshoreblue.com/safety/sart.php — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( On Feb 2, 2018, at 11:42 AM, Damian Greene via CnC-List <email@example.com> wrote: Here's a question for your collective wisdom: We regularly have fog here in Maine, and my normal practice is to hoist a Davis emergency radar reflector in the shrouds (so I hopefully will not get run over by a lobster boat). So this year I decided to get the yard to mount an EchoMax reflector on the mast, and be better prepared. However, reviewing my work-list with the yard maintenance manager yesterday, he asked why I was doing this, as I have radar, and the signal from my radome would light up on other boats' radar better than a reflector. That's something I've never heard before, so I told him I would investigate and get back on that. Frankly, this does not make a lot of sense - why would people bother with radar reflectors - but he has more than 20 years' experience with Hinckley and others. I'd like a definitive answer (Fred?) to resolve this.
