A well logging apparatus is disclosed having an elongate body supporting a plurality of antenna coils housed in recesses formed on the body. A sleeve covers the segment of the body containing the antenna recesses and seals the antennas from borehole fluids. Electronics compartments formed in the body for housing signal conditioning circuitry are likewise sealed by the sleeve. The sleeve includes slotted regions filled with a sealant, the slotted regions being disposed about the antenna coils and providing an electromagnetically transparent window through the sleeve.
