SAMC Antenna Design

Free-standing 20' Vertical Antenna

To construct the 20' Vertical Antenna the following materials were used:

  • 1 each 20' length, 1", schedule 40 PVC (white)(cut off flare and make cutout to expose conduit)
  • 1 each 1" cap for above
  • 2 each 10' length 1/2" metal electrical conduit (the antenna)
  • 1 each coupler for conduit (after clamping cut off excess screw and nipples so that it fits inside PVC)
  • 1 each 10' length, 1 1/4" plastic conduit (gray) (cut off flare and make cutout to expose conduit)
  • 2 each 1 1/4" 2-hole clamps
  • 4 each 1/4" x 2" lag bolts
  • 1 each 5/8" long,1/8" pop-rivet (tack PVC, plastic conduit and electrical conduit together near cutout)
  • 1 each fence post (one side flattened) or 4" X 4" pressure treated post
  • 1 each 4' ground rod (Radio Shack # 15-530)
  • 1 each grounding block (Radio Shack # 15-909)
  • couple feet aluminum ground wire (Radio Shack # 15-035)(between rod and block)
  • 3 each RG-59 twist on F connectors (Radio Shack # 278-227)
  • sufficient RG-59/U or B/U cable to reach receiver (Allied Electronics # 876-9709)(I used about 200')
  • silicone tape (orange)(Radio Shack # 64-2336, a discontinued item so buy it if you can find it)
