[TowerTalk] Molded coax junctions

[Pete Stark K4OM]

Does anyone know the proceedures and materials needed to form molded junctions  (Tee's generally) from rg11 and rg8 size cable.  I have a harness to re-do for an 8 pole 2 meter repeater antenna and I do not trust coax connectors or coax Tee's at 900 feet.  The last harness lasted 25 years and it was of the molded type.  Thanks
