868/915mhz Moxon antenna, tune verifyed by Ibcrazy

thingiverse

Modifyed version of the 868mhz moxon by DzikuVx (Pawel Spychalski). Tune verifyed for 868mhz and 915mhz by Ibcrazy himself. Designed to use rg402 plastic covered coax cable and 1.3mm solid copper wire, you can get it from stripping 220/230v rigid installation cable. You can also use 22/24awg pvc insulated wire or regular servo wire but the swr will be slightly higher but its what most people have and its much easyer to use even if it is a compromise. SWR with the 1.3mm wire is 1.03 for the 868mhz version and 1.06 for the 915mhz version wich is just INSANITY good! For the correct tune the wire should run the entire lenght of the channels and the channels should be filled with glue after the wire is fully seated. The glue is part of the tune, dont skip this, use E6000, epoxy, wellers or some other kind of non conductive non metalic glue. You can also see my method of preparing the coax by making a U shaped cutout in the sheld and bending the center leader, this makes the solder joint of the active element VERY durable. I also made a small L bend on the ground element to get bigger surface area for the solder joint. Cut the wires too long and do the final cut flush with the channel ends after the wire are soldered and mostly seated. Its a good idea to seat the reflector wire before seating the rg402. Added 868 and 915 text to the models, the text prints just fine.
