A QFH antenna has an omnidirectional pattern with enough gain to operate either on the uplink or the downlink for communicating through the various amateur radio satellites that use the 2m and 70cm bands. These 3D printed parts can be…
This is a 3D printed spiral support structure for the wires of a 435 MHz QFH antenna. The antenna provides a dome-shaped hemispherical pattern that is suitable for operation (transmit or receive) on various amateur radio orbiting…
This is a design for an L-Band Helical Antenna support structure (scaffold) that prints completely flat, thus avoiding the printing issues that can crop up with other designs featuring tall skinny elements. It is based up on the…
This is a way to easily make air wound inductors for home made antennas or other electronic gear. It uses a 3D printed coil form and 3D printed strips to hold the turns of wire in place. The model was created in OpenSCAD and is parametric…
I previously uploaded OpenSCAD files for making a do-it-yourself air wound coil (inductor) using a 3D printed form with a taper to allow the finished coil to easily slide off the form. That's still probably the simplest and most effective…
These two files, one for a round boom and one for a square boom, allow the use of whatever choice of boom and element diameters you may want to use instead of being forced to use diameters that fit commercially available brackets. The…
This is a simple spacer for building a 1.5 GHz helical antenna suitable for receiving maritime (Std-C) and aviation (ACARS) broadcasts from the INMARSAT series of geostationary satellites. A video explaining the antenna construction can…
The controller for my heavy duty antenna rotator stopped working properly, but the rotator itself has a DC motor and is easily controlled manually with just a DC supply and an inexpensive PWM controller for speed ramp up/down. To…
These are all currently available results.
