Height of boat v/s mast v/s bridges v/s
My Trawler from the water line to the top of the wheel house is 8 feet 8 inches, However i have 2-8 ft antennas and a SSB/HAM antenna along with my radar dome, i can add the radar dome and its 11 feet 8 inches but the main antennas will need to lay way back killing my transmission distance, My dad claims put the radar dome on a mast about 4 feet Up a mast the anchor light and SSB/HAM antenna at 8 ft , Question is i will be 16 feet above the water line then, From driving a sail boat with a 54ft mast we always wait for bridges but at 16 ft is it worth it ?? also this would allow me to put my Vhf antenna Up right not laying down for travel? any input or ideas are Great ? thanks guys for all the usefull info so far.
