Now there is a better coax choice than 9913, flexible 9913, RG-213, or RG-8. The new Times Microwave Systems LMR® series offers 10 different high-tech, ultra low loss 50 Ohm coaxial cables.
These cables utilize a closed cell foam dielectric with a much higher velocity factor allowing larger center conductor sizes for lower loss. The closed cell foam construction also keeps the center conductor centered, even around tight bends. This keeps the characteristic impedance at 50 Ohms, unlike 9913 which allows the center conductor to shift position and impedance, degrading VSWR performance. The closed cell foam dielectric prevents the water migration problems that were so prevalent in the 9913 type cables. These old designs have air space within the dielectric which allows water vapor condensation to occur, collect, and travel inside the cable, thus ruining the loss and VSWR characteristics.
These new LMR® cables offer a 100% double shield made up of a tough aluminum laminated tape bonded to the dielectric, followed by a tinned copper braided shield for added strength and easy connector installation. Unlike RG-8, RG-213, and other types of braided shield coaxes, the bonded shield prevents water migration between the shield and the dielectric of the cable. Finally, the cables have a tough polyethylene outer jacket for protection against abrasion and ultraviolet breakdown.
