Constructing A Slim Jim Antenna Bow 1 -1/2” Materials 1 - ¾” x 87” Thinwall PVC 200 PSI Pipe (Lowes) 1 - ¾” PVC Cap 1 - 45⁰ ¾” PVC Conduit Male/Female Elbow 2 - 14” Zip Ties 87” 12’ - Paracord 68” Optional 1 - ¼” x 2 -1/4” Eye Bolt (guy line tie) 2 – ¼” Flat Washers 1 - ¼” Lock Washer 1 - ¼” Wing Nut 3 -1/2” 1. Run a length of paracord through the PVC pipe. 2. Bend the PVC pipe until the length of the straight line of the paracord is 68”. 3. Tie the paracord to hold the PVC “curved”. 4. Put curved PVC pipe outside in hot sunlight for 3 -4 days. 5. Optional – Use a heat-gun or a hair dryer to heat the PVC evenly to accept the curve. Caution - if you get a small area too hot, the PVC will bend dramatically too sharp at that point. Bob Ballard – KG 5 SQJ

Mounting The Slim Jim Antenna ~69” 72” After the PVC Pipe Is “Bowed” it will still spring open a bit. 1. Drill a ¼” hole inside the curve of the “Bow” approximately 3 -1/2” from the bottom end of the bow (the end where the PVC Elbow will be attached). 2. Attach the 45⁰ elbow. Place “Bow” on the floor (or flat surface). Re-run paracord through the “bow” and tighten until the length between the inside curved edges of the bow are 72” apart. You will have to estimate where the lower end of the bow is inside the elbow. This will be the final curve shape after the antenna is attached so the tension on the paracord will be what is applied to the antenna. 3. Align a straight line object (PVC pipe, or extra long yard stick) with the lower portion of the gray PVC conduit 45⁰ elbow. 4. Measure 90⁰ straight from the yard stick to the point where that line contacts the ¼” hole you drilled in Step 1. 5. Measure that same distance away from the top of the yard stick where that distance contacts the other end of the inside of the curved PVC Bow and mark that point. Bob Ballard – KG 5 SQJ 4. Drill a ¼” hole inside the curve at that mark that should be approximately 69” from the other ¼” hole. Note - My “bow” is not fully circular so the bottom point was 3 -1/2” from the lower end of PVC “Bow” but the other point was located only 1 -1/2” from the other end of the PVC “Bow” in order to get the 69” needed between the two points.

Attaching The Slim Jim Antenna To The “Bow” PVC Pipe “Bow” Upper end of dual band Slim Jim Antenna 1. Use a 14” Zip Tie. 2. Run the end of the Zip Tie into the end of the PVC Pipe (Note the orientation of the Zip Tie’s “lock”). 3. Feed the end into the inside of the ¼” hole and out toward the antenna mounting hole. 4. Run the Zip Tie through the antenna mounting hole and back into the ¼” hole in the PVC Pipe. 5. Run along side the existing Zip Tie material to the outside end of the PVC Pipe. 6. Feed the Zip Tie end into the “lock” until it locks into place. 7. Pull on the antenna side of the Zip Tie until the Zip Tie’s “lock” feeds into the end of the PVC Pipe and stops at the inside of the ¼” hole (a ¾” PVC Cap on this end of the Pipe is optional). 8. Repeat these steps at the other end of the antenna with another 14” Zip Tie. Bob Ballard – KG 5 SQJ
