Hi J.B. 'multiple vertical wires are fine provided that they converge to a common point as they come down to the feedpoint' That is what the 2 examples show which I mentioned earlier. Thanks for your
Hi Mike & LF, Thanks Mike, I now understand that the reduction of effective height is the reason. So single wire vertical feed & multi wire top is what I should aim for. 73 Gary - G4WGT.
You have the answer at the end of your e-mail. Multiple vertical wires are good for broadbanding, but provide additional capacitance to ground at a low height, thus reducing the effective height. Bro
Hi Rik & LF, I remember seeing a multi top wire LF antenna with multi wire vertical conductors somewhere & I found it in the 'Low Frequency Experimenters Handbook' in an article written by Peter G3LD
Make the vertical of three parallel conductors , each to the centre of each top wire Using multiple vertical wires will increase the antenna capacitance but also decrease the radiation resistance. I
By all means put a wire in the middle for extra pf. but the z shape will make no difference I think. Make the vertical of three parallel conductors , each to the centre of each top wire Bryan g3gvb H
Hi Dick, Cynical responses to your kind of query in the past have been in vein of "Buy another house with more space" Seriously you are up against some basic laws. Empirical test suggest that the min
