Cecil,
Let me show you what I mean about being specific when comparing antennas. You spoke of a "simple" dipole that was not rotatable that had a high gain per Eznec The dipole I believe was for 10 metres with a lobe gain in the order of 10 db, you didn't say what the minimum gain was which is crucial when comparing antennas So I just designed an antenna with a computor program for 160 metres based around a patent write up of mine which probably will not be issued until sometime next year. The beam is rotatable and is at a height of 20 metres. The max gain is 7.35 dbi at 87degrees. Minimum gain at this TOA is a few db less. Compared to another antenna, and that is what you are doing, the gain exceeds a Beverage at any angle over 10 degrees even if the beverage was rotatable. Unlike the Beverage the antenna can be used for transmitting. Now my antenna in the backyard has slightly different dimensions because the material used was available so the gain is down somewhat and ofcourse the ground is not perfect. So Cecil, that is what I mean about supplying relevant data tho perhaps it would be better if I described the antenna as a very SHORT dipole. Cecil you now have a SPECIFIC antenna that can be used for comparison purposes based on keyboard design that is horizontally polarised Cheers Art Unwin KB9MZ PS Nothing wrong with the browser I am just abstaining for a while because of work time limits at this time.
