That should be 1.4" ID. The OD is 2.4 inches

DX Engineering has nicely color coded ferrite - #31 1.4" OD.

You never have to think about what mix is "my ferrite" when you get it from
DX Engineering - it's color coded

Yes, I work for DX Engineering and I am thrilled that DXE has changed the
way you purchase ferrite - with color codes on the cores.

Well I've done it again -- I lost the info on where to order the 1.5 inch
type 31 toroids to use when building chokes to feed antennas.  I have
googled all evening, looked at Mouser, Amidon, etc... and can't find them,
 What really irritates me is I bought them and built three chokes not three
months ago and can't remember where i got them from.  :-( Old age is
agravating.

Who can tell me the good supplier for type 31 1.5 inch diameter cores to
wrap RG142 around?

Thanks,

Dave, K4TO
