May I suggest you take action, rather than just "one might wonder" and toss
out implications of property right infringements, that you call Times
Microwave at 800-TMS-COAX (867-2629), and let them know of your concerns?
Many different companies make RG-8 coax equivalents.....and I haven't heard
anyone complaining about that. The spool is marked "Jefatech", and the
coax is labeled the same way - nothing about "LMR400".
Does that assuage your "wonderment"?
Happy holidays,
