![]() "Ian Jackson" wrote in message ... But, when the coax is stretched, what happens to the characteristic impedance and the loss? [This is a (sort of) serious question!] -- Ian If the ratio of the conductors stay the same, there should not be a change except the losses go up. As you streach the coax, the shield and the center conductor will get smaller. Also the dialectric will have to get smaller. If they do not srink at the same ratio, the impedance will change depending on which conductor gets smaller the fastest. The losses will go up because the center conductor and the outer conductor are smaller. This is the simple IR loss of the conductors. It is the same as going from a rg-8 to a rg-58 type coax. |
