I superimposed the channel 19 contour on the map. and this is what I got. Channel 5 in blue, channel 19 in purple.
Low VHF digital signals are badly plagued by interference, which the coverage map doesn't account for.
The WGBH new location will be the "candelabra tower", now home to WFXT, and WLVI.
If you look through the other FCC forms, especially the 399's - there is a grand plan worked out, which appears to be:
WFXT will move to a temporary side mount antenna and new transmitter at the "CBS tower". WLVI will shut down and begin channel sharing with WHDH on the WHDH antenna. That will clear the top of the candelabra antenna to be rebuilt with the new WGBH antenna and a new multichannel UHF antenna.
WFXT will move back to the candelabra permanently on their new UHF channel. WGBH will move there permanently on their new channel.
WGBX, WBZ, WCVB, and WSBK will move temporarily from the CBS tower to the candelabra tower on their new RF channels.
The shared antenna on the top of the CBS tower, transmission line, and combiners will be replaced at the CBS tower.
WGBX, WBZ, WCVB, and WSBK will move back to the CBS tower, remaining on their new channels.
