| Two that come to mind are 1) does the antenna impedance change with and without the radome? and 2) how is the radiated field affected?

On top of that,
maybe you can also look at the mechanical design of the radome. For example, hardness so that it can protect the antenna inside.

Hi Amir
place the antenna on a VNA and compare with or without radome. If the filter frequecy of antenna moves after placing the radome, you may be able to enlarge,redce the size of the antenna to compensate for the loss and bring antenna backinto frequency with the radome on it
