Where do I pick up the money: the emmy's don't have money, just funny statues or some such junk... you aren't worth the cash, just a good laugh. Excellent pull up AO optimiser Above ground 800 Mhz;inches Put in xyz for centerfed wasvelength for 800 Mhz Put in different numbers for xyz for one wire Source is at the centre a=1 aa=any number say 8 b =2 bb=any number say 10 c=3 cc=any number say 12 dia = 0.1 inches vary aa bb and cc only this gives the program free reign to produce a vertical or a tipped antenna without being guided one way or the other.ie all numbers are different change entry numbers if you like as long as there are no repeats and let the optimizer run where it wants to for resistive impedance , max gain or both. a,b,c are low numbers so the radiator does not drift in terms of height 20 segments per half wave length should be enough. Impedance will come out close to 200 ohms as a guess AND MAXIMUM GAIN OR JUST GAIN OR JUST RESISTIVE IMPEDANCE....YOUR CHOICE. LET EVERYBODY KNOW WHAT YOU GET Now you are on the hot plate at last. Put up or shut up Regards Art KB9MZ......xg |

Put up or shut up not even worth opening the program. for I know that any time you let the optimizer run without realistic bounds and go for maximum gain you are going to get either and unrealizable design or something that no one would want to use anyway. that is what has been fooling you all along, you don't know the limitations of the programs you are using and taking their results as gospel. |
