the only effect you will notice is if the bend is tight enough to move the
conductors enough to change the characteristic impedance. electrons are
moving so slowly compared to the fields that their individual energy is not
affected by physical conditions of the coax in any way that you or I will
ever measure.

hi


just wondering how much and how to calculate the loss in some common
coax for ex lmr400 over a given bend

naturally i mean not to exceed it's bend radius spec

but i figure electrons want to stay in motion and 'prefer' to go
straight so if i make a bend some of that energy i recon will be lost


a 90 degree bend is within spec for the above and i wonder how much i
loose

i know some of my variables lmr400 90bend and for ex 20m and 70cm



thanks
