A radome for a tracking antenna system may include a dome for covering the tracking antenna, wherein the dome includes a dome wall having inner and outer skins sandwiching a low dielectric material layer therebetween, and wherein the dome wall includes a gel coat layer covering the outer skin to protect the dome in a marine environment. The inner and outer skins may have a thicknesses of approximately 0.007 to 0.027 inches, more preferably approximately 0.014 to 0.020 inches, and most preferably 0.017 inches. The low dielectric material layer may have a thickness of approximately 0.153 to 0.173 inches, more preferably approximately 0.160 to 0.166 inches, and most preferably 0.163 inches. The gel coat may have a thickness of approximately 0.010 to 0.030 inches, more preferably approximately 0.017 to 0.023 inches, and most preferably 0.020 inches. The tracking antenna system may include a tracking antenna having a resonant frequency of approximately 3 Hz to 5 Hz., and a radome including a base for supporting the tracking antenna and a dome secured to the base for enclosing the tracking antenna, wherein the base may have a resonant frequency above approximately 10 Hz.
