Outriggers for Hustler BTV vertical antenna

This model provides supports for adding ¼ wave vertical wires as outriggers on a Hustler BTV antenna.  It may also work with other vertical antennae that have a 32mm shaft.   My antenna is a modified Hustler 6BTV and I added wires for 12m, 17m and 80m.  80m is further supported by a tree mounted haul up line.  12m and 17m are wholly supported by the antenna.  ½" schedule 40 PVC pipe is used in addition to the printed parts.  The printed parts are assembled using 4 30mm and  4 40mm M4 screws with captive nuts. Stainless hardware is recommended. Print an upper and lower copy.

Two versions of the outrigger support are possible, 2 way and 3 way.  The 2 way version uses a single length of ½" pvc at each location, arranged as a crossbar, supporting 2 wires.  The 3 way version has an additional mount at right angle to the crossbar which can be used to mount a short length of pipe and support a third wire.  

The clamp consists of 3 models.  The “vert” model is the back clamp of the mount to the antenna.  The “hor” model exists in 2 way and 3 way versions and holds the wire support pipe(s).  On the 3 way version, you can use a 3mm screw  to secure the third pipe or drill and pin if desired.  The “mid” model is the piece in the middle which holds the captive nuts and attaches to both other clamp components.

Two versions of pipe insert wire guides are presented.  One is about 15mm in diameter and correct for the published ID of shedule 40 PVC ½" pipe.  The other is about 17mm in diameter and was printed to accomoddate the schedule 40 PVC ½" pipe sold at the local home improvement store, which was out of spec.   I suggest you measure the ID of the pipe you will be using and use the most appropriate size, scaling as needed with your slicer.  I made the inserts slightly undersized with the intent of using painters tape to adjust for a tight slip fit.   You can also drill and pin if that is preferable.

I printed the mounts without supports & they were acceptable.  Use a high wall count for the mounts to ensure adequate strength around the screw & nut locations.  Use a UV resistant material in the print.
