I put a 2kw on a pole at the stern using a Questus mount. When I questioned
Raymarine they said that it should at least 10' above the water and that
with the new technology use could use the dome as a "pillow" and it would do
you no harm. My system seems to work great and I'm learning more about it
everytime I go out. I built the pole myself using a variety of components.
It mounts the dome, an antenna array, a stern floodlight and the boom and
tackle for the dinghy engine lift. I can send a picture to anyone
interested.
