The 3/8-24 antenna ground-isolator/connector test box is completed. This simply connects or disconnects the lower ground stake connection to the upper counterpoise / coax-feed and vertical whip assembly. It’s easy to have the ground stake connected with the included switch. It uses a $0.69 USD plastic electrical box as the mechanical structure (no 3D printer here). Now just need a nice day here in EN52 to test it out! #HamRadio #VerticalAntenna #AntennaTest #EasyProject
