Transmission Line is too Expensive...

if you have to replace it every few years. Most failures of rigid transmission line are caused by three factors:

  1. Misassembly
  2. Self-contamination due to wear caused by differential expansion.
  3. Excessive heat build-up which causes voltage breakdown.

Only One Transmission Line on the Market Today Prevents These Three Causes of Costly Down-Time:

S.W.R.'s "K"-Line

  1. It is the only line with a bullet that cannot be split by misassembly and a self-aligning flange that protects the insulator and "O"-ring from any damage upon assembly.
  2. It is the only line with one contact joint per 20-foot section with a watchband spring that offers more peripheral contact than the traditional bullet. When it is assembled, it is completely contained within the female cup, which in turn captures all metallic dust and prevents contamination to the insulator.
  3. It is the only line with a patented thermo-couple connector, of all-copper construction, far superior in heat transfer than any other line in the industry. We use only heavy wall inner conductors in all line sizes for maximum heat conductivity.

Whether you're installing a new system or rebuilding your present line, call or fax us for an estimate of what we can do to give reliability and longevity to your system. To have a line that doesn't self-destruct is to have a line that has already paid for itself.
