Bonjour,
I have seen some of these in the course of my visits to EMC laboratories and one of the very good reason to have the door facing the antenna is that when you will have to do the VNSA it will be much easier to align the antennas, regardless of the way you actually perform your measurements (with open or closed doors). On the other hand you will have to decide whether this is more important for you than seeing the setup while testing, one way to do both is by the use of cameras (to see the setup while testing) or having very good marking floor lines from the turntable to the mast. But as it has been point out by others having a dielectric in the path of the measurement can create problems as well, may be a test done on the shelter before it will be secured to the floor would be a good idea if you choose to orient the opening to your control room. May be an orientation of the control room in the path of the setup to antenna could also be considered. Also remember that contamination of the shelter must also be taken into account.

A link to the enclosure link can be seen below. My question is does the door opening to the dome need to be facing the antenna mast while tests are running so that there is no fiberglass between the DUT and the antenna. If we could we would like the door facing the control room so we can see the turntable. Any thoughts would be appreciated.
