Specialized wire antennas frequently require mounting hardware in various configurations to provide mechanical stability. This is a collection of parametric parts designed to assist with constructing various wire antennas.All of these models are parametric and should be easily adjustable to fit your needs.Parts included are:feedpoint -- perfect for mounting the feedpoint of a moxon, loop, or quad antenna on a fiberglass spreader. The hole is tapered to fit common fiberglass rods that can be found in home improvement and hardware stores. Adjust the screw hole size to fit whatever screws you have.adjustable spacer -- print two of these and fasten together with a non-conductive screw, and attach wire ends with ring terminals. This can be used when the antenna needs wire ends held at a specific distance apart, for example, as spacers in a moxon antenna. Adjust slotlen to a bit more than half the length you need (remember, there's two of them) and to allow for adjustment; adjust slotw and holer for your screw sizes. The teeth may need to be cleaned with a hobby knife and/or triangular file for best grip.spreader -- use this to hold wires apart to make your own open wire transmission line. Note that these are not calibrated for any particular impedance, and are designed to snap tightly on to some random wire I found. Adjust wired (wire diameter) and spread to suit your needs. I made this part thin to minimize build time (I need a lot of them), but if you think it is too flimsy, adjust wall for a more stable part. I will use these to construct the matching section for a 20m j-pole, where the spread distance is not critical but needs to be relatively stable. The wires snap in tightly, but if that's not enough, there's a slot for small zip ties at the tip to make it tighter (and parameters to adjust the slot size if needed).
