Such Max Freq:Min Freq tuning ratios are very common.  To add to the list:

SCR-A*-183/-283    2:1 in ALL versions

RU-*               2:1 in RU-2A, -8, -9, -15
                   1.5:1 in ALL other versions

AN/ARC-5           3:1 in R-23, -24
                   2:1 in R-25, -26
                   1.5:1 in R-27
