BURY-FLEXTM was designed by Steve Davis, FCC Licensed K1PEK, principal of
DAVIS RF Co. and Davis Associates. This cable was developed to accomplish
several application needs: 1) to be competitive in durability, flexibility,
and attenuation specs to LMR 400, Belden 9913, 9914, and 9913F (flex), 2) to
be truely buriable and flexible for rotator loops, and 3) to serve HF
through microwave. The results have proven that these goals and quality
standards have been met.
I have no connection with Davis RF Co. Have always received great service.
