Ground plane of my quarter wave antenna
The antenna is a vertical made of aluminium, the first tube is 6meter long is a 100mm in diameter and wall-thickness is 5mm. The next part is a 90mm diameter with 3mm wall-thickness. The top section of the antenna is 10mm in diameter and is only as far as I can remember 60cm. The antenna resonates on 80m. This is the same antenna I use on 160m. I only add a top load.
