RF Delusions

• Are FCC DTV coverage percentages an accurate indication of the audience I can expect?

• • Perhaps, if you don't consider buildings and assume antennas and receivers meet FCC planning factors and ignore the 50% location variability statistic!
  • No, if you consider blockage from buildings and indoor antennas.
  • Treatment of L.R. error code 3 overstates coverage
  • When designing and comparing DTV facilities, use higher signal levels -- I like 68 dBµV/m and 88 dBµV/m
