Cutting chart for MAXRAD BMFT120 1/4 wave?

Anybody have a cutting chart for the Maxrad BMFT120 1/4 wave vertical? I need the length for 448 MHz.

The chart with the antenna lists lengths for VHF high band and 800 MHz for the BMFT120, and for VHF high band and UHF for the MWB1320 wide band 1/4 wave. Unfortunately I can't find anything for UHF for the BMFT120, and since the VHF high band lengths are different for the same frequency for the BMFT120 and MWB1320 I'm assuming the UHF lengths will be different too.

Thanks in advance,

Makes great sense, right? I've got about 8 BMFT120s on the roof of the truck... they don't come with charts for UHF anymore. Dunno why.

Let me go through a few data points, and you can draw out your own graph:

UHF:
405MHz - 6.60"
430MHz - 6.25"
447MHz - 6.00"
469MHz - 5.75"
484MHz - 5.50"

If you want to be fancy, enter the data into Excel and draw a graph from there.
