Radar reflectors, do they really work?

[GJ0KYZ]

I have an Echomax reflector on my boat and no one had collided with me yet. If you have radar you will know that even a large yacht without a reflector will show a weaker echo when end on than a smaller boat that does have a reflector. They're relatively cheap so why not fit one?

Taking that to it's logical conclusion - I've never had one at all, and nobody's ever run into me........

On a more serious note, those of you "with", how do you fit them to avoid masking the all round white & VHF aerial for a good chunk of their 360 degrees radiance? Under the crossbar makes sense, but then it's almost level with the engine, and will be partially masked by you & your crew.......

As below, top of vhf antenna does seem close to top of reflector. Will keep an eye/ear on this? Both as fitted by manufacturer.
