JPC-7 Antenna Spiderpole Adapter
thingiverse
This adapter screws into a JPC-7 Dipole Antenna Hub and slips into the top of the 7th pole section of a Spiderpole telescopic mast. To use remove sections 8 through 12 of the Spiderpole. This allows the antenna to be used at a 7m height which is ideal for 15m and 10m HF operation. Will also work respectfully on the 20m band. For added strength, install a #10-32 x 2" machine screw and nut. If the part fails for any reason, the screw will provide some reinforcement. I included the step files so that this can be modified for other pole section diameters.
