Long boom Vs Stacked elements

Jus' wonder. Does Art read what he writes, after he writes it and does he understand what he wrote? Or are those just fragments of his elaborate train of thought making it onto the I-waves and puzzling the rest of us dummies? Snip shield on! Here is the challenge for the antenna designer: Design antenna that on transmit will radiate with some 15 dB gain in all directions and on receive be capable of sharp beam control in H and V planes, infinite F/b and F/rest of course. I WANT ONE!!!!! Dave WD9BDZ Yuri, K3BU "Richard Clark" wrote in message ... On 21 Oct 2006 19:44:50 -0700, "art" wrote: Well, basically nothing. So, at the expense of bandwidth let's run that list once again: Hi Art, To date, EVERY posting that you've made in several weeks has missed 100% of the following: 1. What frequency? 2. What design style? 3. What gain? 4. What f/b? 5. What f/s? 6. What feedpoint impedance? 7. What bandwidth? 8. What height? 9. What optimum launch angle? 10. How many elements? 11. What spacings? 12. What lengths? 13. What orientations? 14. What method of feed? 15. What forms of loading? Issues 1,3,4,5,6,7,8,9,10,11,and 12 all require numeric responses. Issues 2,13,14, and 15 demand ordinary mechanical descriptions of conventional devices. If the numbers and ordinary mechanical descriptions do not bear out anything remarkable, you can be sure this will be a short thread. It's that simple. 73's Richard Clark, KB7QHC |
