As the boat moves, the self-levelling mechanism continuously compensates — so your GPS or VHF antenna stays optimally oriented for signal reception, regardless of what the sea or the deck angle is doing.\u003c\/p\u003e\n\n\u003cp\u003eFor GPS antennas in particular, maintaining a level, upward-facing orientation directly affects fix accuracy and satellite acquisition. For VHF, a vertical antenna radiates its signal in the correct horizontal plane — tilt it and you lose range in the directions that matter most.
