someone could bring up some examples of this happening, with details?

The largest Decibel, Sinclair, Telewave or similar folded dipole

Antennas are probably the only part of the free lunch rule...

There are two types... the standard folded dipole

Hi Larry, yeah... reading back through it I transposed 408 and 420.
Nate, perhaps you could clarify that paragraph...

Going to the higher gain antenna may cause shadowing in some areas
close in to the repeater site if its up real high. I also like the
DB-408 antennas and am using them on my systems. The fiberglass
antennas are OK also, But if they take a lightning hit they are gone.
