I ran Top Band from a 2nd story apartment with a full-sized inverted L hidden
in a tree, with radials running down the sides of the bldg., and worked 93
countries with 100-600W. 73 and GL, JH W6UQZ
Yes on all counts.
My neighbor, W6GJB, has built a portable high power magnetic loop from
eight 4-ft sections of the modular portable military surplus 2-in
antenna masts. Four sections have two 45 degree bends in them, and serve
as corners, and fit together to form a small loop. Four straight
sections are added between the bent sections to form a larger loop. He's
tuning with some big rotary plate capacitors in parallel with fixed high
voltage caps from my junk box.
I agree with others that the usefulness of an indoor loop will be quite
limited. W6GJB has done fairly well running QRP with the smaller "Alex
Loop" on 40M and above from hotel rooms in wood frame buildings.
