Now that I am about to install my 8-L 6-M InnovAntennas yagi, I found that I need a 46-foot (14m) length of cable for that project. This cable will connect from the Driven Element, along the boom, down the mast, around the rotor, and connect to the 1-5/8" Heliax feedline. Times LMR 600 was suggested as the cable to use but since it has to flex whenever the rotor turns, I began to look for another solution. In looking at the M&P website, I felt that their HYPERFLEX 13/.500" cable would do as good a job or better than the LMR600. M&P cable has 37x0.56mm copper wires. I felt this was better for a cable that was being flexed as the antenna rotated. At 50 MHz the M&P has 0.6 dB loss and the LMR 600 has 0.5 dB loss per 100 feet. That means the extra loss with the M&P cable in my installation would be less than 0.05 dB. Also, the M&P cable claims to have 100% screening where the LMR 600 says >90%.
Therefore I ordered the 46-foot (14m) length of HYPERFLEX 13/.500" with a soldered N-Male connector installed (for the antenna end) and a 7/16" DIN Male for the end that will connect to the Heliax. I also ordered a 3-foot piece with N-connectors on each end for an in-shack jumper. Now here is where it gets amazing!
When I unboxed the order, I found the 46m length of cable (with connectors installed) neatly coiled and wrapped in plastic (see photo at upper right - click on any photo to see a larger image.) Also the 3-foot piece with N-connectors was in its own plastic bag and it included a Test Report where M&P had connected that particular cable to an analyzer and printed out a TEST REPORT for the Return Loss and Impedance of that piece of cable from 100 kHz to 200 MHz (see the image on the left.) WOOF! I am totally impressed and MORE than pleased.
I should also mention that the cables are secured with very nice Velcro straps with the M&P logo. AND, a lens cleaning cloth is also enclosed. You can see that cloth in the center of the upper right photo with the phrase "The DXers PRO Choice:" on it. Yep! You can bet that M&P is MY choice for cables in the future.
