Hi It is very much a 12V antenna. It also is a “50 db gain” antenna as well. Most of the timing gear is looking for 20 to 30 db less gain than that in an antenna. The good news is that you can run a really big splitter after one to drive lots of stuff. The bad news is that you may still need attenuators.
Looking at the snow piles on my GPS antennas, I would not recommend using the ground plane. It will significantly increase the load on the mount ….
