.031 Coaxial Cable – Semi-Rigid Copper – Low-Loss
EZ-31-LA
⌀.031" Semi-Rigid Copper Outer Conductor, SPCW Center Conductor, LD PTFE Dielectric. Low-Loss.

EZ Form copper jacketed semi-rigid LA (Low Attenuation) cables feature a microporous dielectric, that facilitates lower attenuation, higher operating temperatures and greater phase stability vs. temperature when compared to solid PTFE semi-rigid cables.
To impede oxidation, we recommend keeping this product in its original packaging and storing it in a dry temperature controlled environment until consumed.
Additional information unique to microporous dielectrics:
