Home brew tracking generator cable
|
Six individual cables interconnect the HP 141T and the 8443A. |
 |
Each cable is an equal length of RG 174/U coax and two home brew connectors. |
 |
Each connector is made from hobby type 5/32" brass tubing 1 1/4" long. Original OD was .156", I turned down one half inch of the tube to .151" in my drill press using files and emery cloth Approximately 3/8" of brass tubing is exposed beyond the heatshrink. |
 |
The center conductor pin was salvaged from a db9 female connector. The white insulation is stripped from number 14 house wire No attempt was made to solder the shield of the coax to the brass tube. The outer surface of the brass tube was shined up with emery cloth The shield was placed over the out side of the tube and heat shrink tubing holds it all in place. The cables have been in operation for 3 years and still working. |
