Moxon UHF TV antenna for DVB-T - fully parametrized

thingiverse

This small indoor TV antenna project is designed to pick up DVB-T UHF signals. The Moxon antenna itself is made of two active L-shaped parts in front and one reflector part at the back. It's directional, providing about 5dB gain. You can learn more about this antenna design by visiting http://en.wikipedia.org/wiki/Moxon_antenna. The antenna frame consists of identical upper and lower halves that fit together to hold the wire antennas in place. The wires are attached with screws. The frame is built to be strong, ensuring it holds everything together well. The antenna stand has three main parts: a rotor plate, a stem, and a foot. The foot resembles an X and includes holes for 75mm or 50mm VESA mounts at the rear of most TV sets. You can mount this onto a flat surface as well as use it to secure to a standard VESA mount on your television. To achieve optimal performance for any UHF channel, simply modify the dimensions in the SCAD file until you find resonance frequency matching that specific signal's needs. Use Paul Evans' Moxon antenna calculator located at http://w4.vp9kf.com/moxon_design.htm to fine tune your parameters. Preconfigured setups exist for channels 24(498MHz), 36(594MHz), 48(690MHz), and 60(786MHz). The calculator used in generating these settings can be accessed from the provided link, giving users four different choices to choose their perfect UHF channel. If unsure about selecting a suitable channel frequency, I suggest starting with Ch48/690MHz like I did during my own experience. For this, print out both the frame halves. Use any robust wire (with diameters ranging between 2-3mm) for the L-wire pieces and the single longer U-shaped part, as detailed in Picture #3. Try using aluminum, copper, or brass if possible; otherwise, regular household materials like a coat hanger will work fine. Place the wires inside the grooves carefully, securing both halves together using M3x12 screws or nylon fasteners. Assembling these requires a combination of patience and manual dexterity. Connect your antenna cable by soldering its central conductor to one end of an L-wire and shielded part to another end. Finally, complete the construction process by putting everything in place – this will require additional components, including 4 screws for attaching it directly onto a VESA mount at your television's rear if needed.
