Case for simple QRP Endfed Transformer
thingiverse
Case for a simple QRP broadband transformer for a half wave end fed (HWEF) Antenna. In this case, the transformer is for the 11m Band (CB-Band). The Antenna itself is an about 0.95*Lambda/2 wire. You should a current balun into the coax about 1-2m from the transformer to the TRX. This helps to keep HF out of your shack and use the coax as counterpoise. There is also a file with a Meshmixer Support added to the holes if required. The top of the case can be fixed with M3 screws, but you need to drill the thread into the plastic.
