Antenna & RF Feed-Thru Insulators

This dandy beehive is removed from service but is in excellent, reusable condition. Two piece construction is sandwiched with 2 rubber gaskets and a ground ring which has a 4" braid and 0.5-1" hose clamp attached. The max body diameter is 3" while the bottom half is 2.6"H and the top is 1.75"H not including the adapter. The top half inserts 1.87" into the bottom beehive with a 1.75"D internal insulator body. The top is adorned with a "UHF" female connector or S0-239 whose center pin feeds through the insulator bowl to the inside terminating with a 5/16" fine thread stud flush with the bottom of the internal insulator body. This length stops short of feeding all the way through the insulator and thus leaves no ready solution for affixing the two halves over a metal chassis or frame. The original installation must have had a long barrel nut that reached through the bottom bowl to screw onto the center conductor and then to the feedline. The end of this 5/16" stud measures 1.15" up inside the bottom with both halves clammed together without an additional wall thickness. A "UHF" to longwire thumbscrew connector is included. It is solid metal / silver and shorts the center to the "UHF" threads but the outer threads were isolated anyway. By this means, the longwire attachment mechanism is strong and durable.
