This model was developed to support portable amateur radio activities such as Parks on the Air and Summits on the Air activations. It has a space to hold a 1:49 transformer made with a FairRite FT240-43 toroid, a SO-239 UHF connector and wire winder that can neatly store up to 140 feet of light antenna wire such as Polystealth-26. Its light weight and small size make it ideal for use in portable operations. It's not meant for continuous use outside. Successful models have been printed using both PLA and PETG, 0.25mm layer thickness and 20% infill.
