Re: How much loss will this 3cm feed have ?

Sharp right angle N adapters do not behave themselves at 10GHz - there's a nasty mismatch in there. You'd do better to replace it with a semi-rigid coax with, ideally, N connectors or even SMA with N adapters.
When we used a sharp right angle at 12GHz for th GB3SCK beacon, there was something like 20dB signal loss. I don't recall measuring at 10GHz, but certainly wouldn't trust it above around 6GHz
