RG400 cable is equal to RG142 but more flexible thanks to the stranded inner conducor

Here there are the some tests made in our laboratory to demonstrate the quality of the cable up to 12 GHz even if the manufacturers specify it for a maximum frequency of 6 GHz.

This cable is suggested for applications where it is needed a high shielding, high power and also in the presence of high temperatures, in fact the PTFE insulation can work up to 165 °C.

We also made a test on the variation of attenuation by flexing the cable, the graphs show the normalized variation.
