Return loss is the negative of the magnitude of the reflection coefficient in dB. Since power is proportional to the square of the voltage, return loss is given by, where the vertical bars indicate magnitude.eturn loss is the negative of the magnitude of the reflection coefficient in dB.

Welcome. Why Repipe, When you can ePIPE! ePIPE provides a solution for plumbing system failures such as pinhole leaks and slab leaks, corrosion control, low water flow, and lead/copper contaminants. ePIPE is an affordable, effective, and less disruptive alternative to an ordinary re-pipe.
Solvent Cement For Plastic Pipes. Here is my solvent cement primer, pun intended. Modern plumbing pipe, especially drain pipe, is almost all plastic. Most of the plastics involved must be joined with glue, solvent-cement. This makes knowledge of the plastics and the solvent-cement for each important.
