"Big Endian" wrote Actually I want to monitor the antenna because I have a splice in the feedline and the feedpoint is subject to wx, snow ice and rain. Some times the feedline itself is covered with snow and ice. I would find it interesting to see what is happening when I see my SWR shoot up and retuning my matchbox. I also have a strange thing happen when I apply high power, I get a slight bump up in SWR suddenly. I often wonder if one of my end insulators are breaking down under 1KW of RF or if there is some imbalance on one leg due to ground or trees swaying in the wind. ======================================= Perhaps you should have mentioned all this in your original enquiry. The people you expect replies from are not mind readers! It was clear enough to everyone else that he wanted to know how to make measurements. It was also clear enough for you to declare that measurements are not necessary. Maybe this is a good time to remind you of your own favourite quotation: "When you can measure what you are speaking about and express it in numbers you know something about it. But when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind. It may be the beginning of knowledge but you have scarcely in your thoughts advanced to the state of science." William Thomson, Lord Kelvin, 1824-1907. -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek |
