I'm looking for some basic measurements of a Firecracker Antenna. I need to draw one up in CAD and 3D print it for a 1/29 scale detailing project (along with a bunch of other detail parts). Does anyone have some basic measurements, or up close photos? The basic design is pretty simple, but it would be nice to be able to scale it accurately. Here is the basic shape. I wasn't sure if it was a 4 bolt or 6 bolt pattern that holds it on the roof? cad.onshape.com/documents/03647d7a536b38a195cc2535/w/69f40ced2c01aa8c16f1e36f/e/a137222126fe82bec68e9c9bCraig

Craig, the Motorola firecracker-style antenna measures 11-1/2 inches high and 3 inches in diameter. The mount is a four-hole configuration and the cover is held on with two 1/4-inch hex head screw fasteners at the bottom sides of the cover, 180 degrees opposite each other.

Thanks for that information. I'm guessing that the mounting pole is about 1.5" or 1" in diameter?
Is that height the overall height from base to top of antenna or just the distance of the actual antenna?

Height measurement is from base to top of antenna. The conduit is one inch in diameter.
