(partial faraday cage w/ reinforced concrete, steel mesh, AC lines around perimeter, cladding, bad windows, lift, etc)
Years ago I tried a few different designs, and even had a SOTA beam pointed out the window with a weight attached temporarily (Flats on the Air?!).
Then ended up with a 2E0ERO mag loop before recently settling on a smaller mag loop from China pressed against the window facing southeast which has allowed 20m and 30m weak signal digital modes to work quite well, particularly in the mornings, averaging at around -15dB around Central Europe which is ‘fine’ for a few FT8 QSOs when conditions aren’t too bad.
The next plan is to try a random wire on fibreglass stand-offs in an L/V shape (it’s a corner flat) with indoor counterpoise.
I’ll let you know how it goes, but would love to hear from anyone who has experimented with HF from buildings like this where roof access is restricted :)
