Are you saying they should have kept high power levels and lived with the distortions in coverage that a side-mounted antenna produces? That doesn't seem wise at all given that ATSC does poorly with multipath.
No one is going to want a 20 year old VHF antenna, especially one that requires increased transmitter power to utilize. While a fully cross polarized or circularly polarized antenna would solve some viewer problems, the truth is that the stations are not willing to bear the cost of increased operating expenses nor the capital expense.
Fifty years ago, the viewer had to endure the expense of outdoor antennas, towers and quality transmission line for reliable off-air reception. Those days have returned.
