BURY-FLEXTM was designed by Steve Davis, FCC Licensed K1PEK, one of the principals of DAVIS RF Co. 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 TRULY 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.
BURY-FLEXTM is a 50 ohm cable with double shield yielding 100% shield coverage, consisting of a 97% braid shield which is tinned for ease of soldering and corrosion protection, PLUS a bonded foil shield for added moisture protection. The velocity factor is 82%. With a loss factor of 2.9 dB/100 ft @ 400 MHz, it is quite competitive with 9913 and LMR 400 (the latter which requires expensive connectors). BURY-FLEXTM uses standard PL-259's or the standard N connector, available from us. Quite important is the fact that this cable uses a PE (Polyethylene) outer jacket which is highly abrasion resistant, as compared to PVC which is not nearly as durable. This product is direct buriable and PE is non-contaminating to its dielectric or to other cables it is bundled with. PLEASE NOTE: You should use this product for its various advantages even if you do not need to bury it as the low cost, and average of only 82 cents a foot is well worth all of the other benefits alone. Commercial entities are pleased with its tough, high durometer, outer jacket and many hams can lay this cable in grass and woods without worry of abrasion or animal gnawing. |

| Notes: * Bury-Flex attenuation is very close to LMR400 (2.1 dB @ 400 MHz) ** RG-8 (#WM106) {Not listed on table} has somewhat higher attenuations as compared to Bury-Flex (note that Bury-Flex has a 20+ year abrasive resistant jacket of PE, whereas RG-8 is a Non-Contaminating PVC). RG-8 (WM106) has a double shield. *** RF9913 (#WM102) Flexi-XL is stranded. Attenuation is slightly higher than standard 9914, but still very low loss. |
