I am about to install a radar system on my 34 MKII and I will be using a mast mounted radome scanner/antenna.I recently purchased a 4kw, 24 inch Raymarine Radome and now I am thinking that the 2kw, 18 inch unit is better suited.... I understand the operating differences between the two but my concern is the size and how it will interfer with the sail and the look of a larger unit on the mast....Any thoughts on keeping the 4kw or should I install the 2kw? Thanks
