Picked up some supplies for the latest construction. Thus far, this design outperforms all others I’ve tried by a considerable margin. The bulk of the design relies on a SO-239 UHF socket adapter used for the antenna body, jacketed 12 gauge solid core house wire for the antenna elements, crimp-on eye terminals, some machine screws, and a bunch of PVC pipe and fittings. Heat shrink tubing, epoxy, and more heat shrink are used to complete the finish for the work.
If the opportunity is present, I intend to make a similar 5/8 wave model using a similar construction method for comparison prior to deciding upon what gets mounted to the exterior of my QTH.
