The OpenScad file has been provided to allow for customization of your available fasteners. I recommend that you OUTPUT the BOLT & NUT test template first. Ensure that your fasteners are correct. Then print the antenna mount kit (x3).
A base to hold this antenna has been posted at this link:

Please view the instructions inside the openscad file near the top for details. Everything is well commented.
This is an Indoor antenna. To be installed in the Attic or wind sheltered area at your home. It requires a minimal number of parts, mostly 3d printed parts.
- No print supports required
- Infill: 20%
- Shells: 2
Layer Height: 0.20mm
Print ...the following parts:
1x HDTV_ATSC_screw_test.stl (test your fasteners)
3x HDTV_ATSC_mblocks.stl (mast block, >1" diameter pole)
or, 3x HDTV_ATSC_mblocks_sm.stl (mast block < 1" diameter pole)
3x HDTV_ATSC_wire_block.stl
Fasteners required:
The prebuilt STL files are configured for the following fasteners:
(6x) 8-32 screws ( 2.5" or longer )
(6x) 8-32 nuts
(6x) #4 machine screws (1/2" long)
(2x) 5' (60" x2) 12 gauge aluminum drop ceiling wire (HomeDepot / Lowes)
Customize
- This project uses the Write.scad text generator and orbitron.dxf font to label many parts. Please grab these files as well from my project files section or from http://www.thingiverse.com/thing:16193 (many thanks to HarlanDMii )
- Edit the HDTV_ATSC_Antenna.scad file and adjust the fastener settings below the instructions section.
- Set the variable OUTPUT=0 and compile the "BOLT & NUT" test strip. It will print in <20 minutes.
- Test your fasteners in the test strip.
- Compile the MastBlock
- Compile the WireBlock with your fastener settings.
- Print the MastBlocks x3 and WireBlocks 3.
Extra Parts:
- RG6 cable to connect from TV to antenna
- 75 ohm to 300 ohm matching transformer (aka balun) @ RadioShack/TheSource
- mast or pole to mount your antenna. 1inch electrical pvc pipe makes a good light post
- UHF antenna signal booster to reach more distant channels
Assembly instructions:
- Create your wire elements. (follow the instructions as per file: Instructions-SBGH_Wire_Elements.pdf in the Files section).
- Assemble each mast and wire block into a complete block.
- Install each block on the mast
- Align each block with the wire elements that you have created
- Install the wire cover screw on one side to hold one of the elements
- Then install the 2nd screw in the wire cover to hold the other element in place
- be sure that each part of the wire element is aligned with each other. Straight wire elements receive the best channels.
- Some channels may require that you install a deflector behind your antenna. This will be a future add on to this antenna design.
- Connect the antenna to your HD TV tuner input with an RG6 cable.
- If you do not receive many channels, add a signal booster to the cable. available at (eBay / Channelmaster.com / RadioShack / HomeDepot) and other stores.
I receive 23 channels on this antenna (attic installation) in Southern Ontario. Depending on your location, and installation height above ground level, more channels may be received.
I hope that you enjoy this antenna. It has been a long time in the making.
- ABS plastic
- 6 (8-32) long screws (70mm / 2.5" or longer)
- 6 (8-32) nuts for the long screws
- 6 (#4) short screws (6mm / 1/2" long)
- 2 (60" / 1525mm) lengths of aluminum 12 gauge wires.
- 1 - mounting pole (1" / 25mm diameter or larger) @ 1 meter/3ft tall (minimum)
- 1 - 75ohm to 300 ohm matching transformer/balun
Designer
cpayne3d3d model description
I designed this HD TV antenna in OpenScad. It was designed with as few components as possible. To allow everybody to benefit from ATSC over the air TV... broadcasts. References previous element design by Doyt Hoverman.The OpenScad file has been provided to allow for customization of your available fasteners. I recommend that you OUTPUT the BOLT & NUT test template first. Ensure that your fasteners are correct. Then print the antenna mount kit (x3).
