ABSTRACT:
Heat dissipation problems in a sealed radar antenna unit are avoided in a construction including a generally cylindrical body (10) of metal having opposed ends (12, 14) and an interior, cone shaped chamber (16). The cone shaped chamber (16) has a wide opening (18) at the end (12) at a narrow opening (20) at the end (14). A plurality of peripheral grooves (30, 32, 34, 36 and 38) extend about the periphery of the body (10) between the ends (12), (14) thereof to define heat dissipating fins (40) integral with the body (10).
