Why are there no 6-meter, 2-meter, or 0.7-meter frequency bands

Thank you for your reply，Sorry, I didn't describe it clearly. What I meant was why there is no frequency band mentioned earlier in amateur radio propagation prediction。

Clearly because our propogation tool uses VOACAP for the data which is free professional high-frequency (3-30 MHz) propagation prediction software from NTIA / ITS, originally developed for Voice of America (VOA).

Thats why we dont include frequencies above 30mhz
