About 30 years ago, I worked for an MATV contractor who had lots of
installations in high rise buildings on Chicago's Lake Shore Drive, in the
shadow of VHF and UHF transmitters on Hancock and Sears, and with
transmitting antennas having very little directivity in the vertical plane (1
and 2-bay on 2-6, 3 bays on 7, 4 on 9 and 11). VERY well shielded cable was
absolutely necessary for these installations -- anything less simply would
not work!

Dunno -- perhaps in very densely populated VHF/UHF sites? I would certainly
defer to those with far more experience in that world than I.
