### ⭐⭐⭐⭐⭐ Wow! This Cable Means Business
*by T***Y on April 19, 2020*

I purchased this cable to connect my Wilson 4G LTE directional antenna to my MOFI 4500 and WOW! This combo increased my down and up speeds by over 10Mbps! I am very impressed with the quality of this cable and you definitely get what you pay for as there are much cheaper cables out there but they won't hold signal anywhere near what this cable provides! It is costly but for solid 4G signal, well worth it! The only caveat, although necessary due to the quality of the cable, is it is rather difficult to work with since it is so thick.
