Like yourself, I am forbidden to have an outdoor antenna. I use the ''issue'' one, which is on my windowsill ,and when ''operational'' ,make a small ''tower'' of books with a round biscuit tin on top as an aerial mount. I am three floors up, and live under the glide slope for LHR 27R. My ''live'' coverage is'nt bad, sometimes over 60, though I rely heavily on live network to cover my blind spot, which is mainly to the NE.
