How is tx & rx antenna VSWR effected by the antennas being inside a metal shed or aircraft hangar?

in this scenario the TX & Rx are both inside the metal enclosure, so how would that affect the SWR?
SWR is really a transmission line matching term to the receive or transmit nodes from a matching network to the actual antenna in a system of parts. The actual antenna impedance changes (in reactance and radiation resistance) with just about any change in position or surroundings. For X static scenario a properly tuned and designed matching network could reduce reflected power to near the zero mark.

If the distance between the antenna and the wall is an integer multiple or fraction of the wavelength,
then the wave will have a null or max at the antenna.

Think of the skipping rope attached to a wall,
waggle one end up and down, at certain frequencies , you end up with max and min static on the rope,

thanks, and will either of the two, min or max then effect the rx antenna VSWR (in the line)?
