Alpha Delta Dipole Antenna Replacement Arc Plug™ (SEP)
The ALP-SEP Arc-Plug protector which is mounted in the DELTA-C center insulator bleeds off slow rising static electricity charges routing them harmlessly to ground, before they can enter the shack thru the feedline. This is far more effective than DC grounded baluns or chokes, which can be "popped" by static charges. Dangerous static charges are developed from thunderstorms, high wind driven snow or desert sand, and have been measured to 1,000’s of volts; so potent, they can puncture the dielectric of unterminated coax.
The SEP is located in the back of the DELTA-C center insulator, and is easily replaced by carefully removing the #10 stainless steel hardware used to attach the ends of the antenna wires. Please note the assembly order of the washers, lockwashers, wires and nuts and carefully re-assemble in the same order after replacing the SEP cartridge.
