Yes. They work well and it has more than enough gain as long as the cable leength is reasonable. Use the cable TV type RG6 with waterproof F connectors. Those really are waterproof. Then get a F to "whatever" adaptor for the cable to antenna. Actually it hardly matters if the connection is water proof because it is make inside the 1 inch pipe. That is the other advantage of this type antenna: It mounts on a pipe. So get the longest pipe you can manage and get the antenna out into free space and far from reflections and so on and with a good view of the horizon. Location is far more importance then the brand of antenna or the type of cable. Put with the abilty to mount on a tall mast you can get a good location. If this antenna works better it will be because of the better location more so then because of the antenna The pipe is not that expensive and doubles as a conduit for the cable. But do remember to ground the pipe. Give lightening an easy and direct path to ground and it will follow that route.
