There were some that came out in the late 1970s looked like a large globe or ball ,they were a sealed for life unit and came with great blag how good they were with state of the art secret internals.

Secret internals what a joke.... we cut one in half and basicly it was 4 very corroded metal reflector blades that floated on a foam raft in a bath of antifreeze with a weight on the bottom so it kept upright ,,,worked bit like a liquid filled compass ,,
they were really expensive too, but after a couple of years the reflective surfaces began to corrode away or the foam had soaked up the antifreeze making the thing useless.

Yes in principle. Having seen the regular "my cheap VHF aerial bracket has snapped" threads I expect that it would need to be a properly engineered solution which would cost more than an echomax or trilens.

Bear in mind that the electronics / software in modern radar are quire sophisticated - they are specifically designed to remove spurious noise.

Mark, although I am sure the MAIB wouldn't object in principle to sharing the information - that publication is copyright MAIB/QinetiQ and so probably shouldn't be hosted here.

The good news is there is a copy on the MAIB website - along with some interesting stuff on visual acuity of people wearing photochormic (a.k.a. reactalight) specs at night: http://www.maib.gov.uk/cms_resources...zo_Annexes.pdf

Thanks, I understand. The Pdf-file on my computer isn't the same, it's more extensive with more focus on smaller craft.

Ah, I think I posted the wrong link - I will post the right one later.

EDIT: Here is the correct link: http://www.maib.gov.uk/cms_resources/Radar reflectors report.pdf
