Well, thats what my latest project is affectionally being called.
In reality, it is a 2.5m anechoic chamber for testing marine radar transmitters.
It took my almost 3 weeks to build this. It is possibly the biggest thing I have built for some time. It is capable of taking a 2m open array.
There is £35K sat here.
Even the screwdrivers cost £45 each. They are made from 6AI-4V titanium though.
You have to use non ferous tools when working with radar to prevent degaussing the magnatron, which would trash the unit being tested.
