(sorry for dumb question)

Thanks in advance!

it is simply 5cm of 2.5mm thick wire
its a strip line tuned circuit for uhf amplifer

not all inductors need to round
flat ones at high frequencies are more ridgid therefore cause less drift in value
and also have easier more predicatable charicteristics

Thanks it's clear now!
I thought that CM is something special abbreviation :D
