I think the 2.53(0.05 dB) number is a typo. He doesn't even say which antenna he is talking about in that paragraph. Assuming it is the Figure 4 graph, the gain difference, looking at his graph versu
The computations for the graphs were done in NEC2, which, as I understand it, has some shortcomings in dealing with wires near ground. I'd have to see some serious measured data before I placed any c
I have done some tests with a horizontal loop and putting a reflector underneath... Also, one year we had Field Day at my place and had an 80 meter horizontal loop at 35 feet with a reflector loop ab
Unless someone has access to NEC-4 or some even more restricted military software the best you can do is guess when over anything but perfect ground. Here is where actual work in the great outdoors h
