1/ The PIN shall be the number shown and a four-digit number indicating the nominal relaxed length in inches.
2/ The VSWR value for any length between the lengths specified shall be the next higher value (e.g., for a 15-inch
length of M287/03-01, the VSWR would be 1.06:1).
3/ CU = copper alloy, AL = aluminum alloy.

4/ These assemblies are constructed from beryllium copper and the flexure cycle is 10 rather than 10 . All other
characteristics are as listed.
