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. LMR 600 has a solid center conductor and the 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.
an excellent example of great service and getting what your paying for and more good choice and good many dx 73 john w8wej
ReplyDeleteI also had excellent an fast service from this company. I'm also enjoying the Velcro straps that came with it, more useful than just around cables. WD6Y
