Testing Results for US Made LMR Coax
Attenuation (Signal Loss) per 100/ft – (lower numbers are better)
Attention: There are many unknown companies quoting the same specs as Times Microwave and Andrew
/ Commscope Coaxial cable.
There are some issues with this:
- Cheaper grades of cable may Start
with the same loss but can quickly degrade over time with
significant signal loss.
- The Inner foil layer below the braided shield is bonded to the
foam dielectric in a patented process that prevents signal leakage and
moisture infiltration Only on US Made Times Microwave Coaxial Cable.
- True Mil Spec testing criteria is not followed by many Chinese offshore
producers and when retested by UL cable has repeatedly failed to pass
muster.
- When subjected to standardized quality testing – Jacket materials, Copper alloys, and Dielectric Foam
have been found to be adulterated and containing contaminants.
- While there are quality Coaxial Cable producers in China and other offshore locations
they mainly produce cable for major brand name retailers who provide
their own quality control, and do not sell off cable under “generic” or offbrand names.
Coax Cable Loss is Frequency Dependent – The Higher your Frequency the More
Important your Coax Loss Is Measured in DB per 100 feet
