Tinky With With A Weird Antenna or Aerial That Looks Like A Treble Clef (Made By Someone?)

In a few Teletubbies episodes, some Teletubbies have the wrong antennas on, like if Tinky Winky's antenna is a treble clef-like or circle instead of a triangle, Dipsy has no antenna, Laa-Laa's antenna is a straight instead of a curl, Po has a square or triangle instead of the circular antenna, etc.
