i was thinking about building a bi quad.
i can get plenty of sheet aluminum , im confident i can make a good connection to the aluminum ( so no issue there ) . all other parts would be copper or non conductive .
id say the aluminum i was going to use would be at least 1/8 in .
if im shooting for ALL of the potential 9 db i might get from an ib crazy bi quad . if anyone could guess what loss there might be , if any ?
