S A s are usefull for antenna hobbyists. maybe you should hook one up to your magical neutrino antenna and see if you can measure the weak force tilt frequency in your drunken vertical. David You have stated that you have the smaller AO program (limited in pulses) but as yet you have not proved to anybody that you know how to use it !. If you insert dimensions for a vertical radiator where none of the dimensions for XY and Z are repeatable then the program gives you picture of the weak force and it's angular direction ..Not only that my friend, it also shows that with the use of this vector ( the weak force remember) it shows what the position the radiator must take up for maximum gain !. Drunken vertical indeed! On the other hand you can continue the mistaken idea that intercoupling of radiators provides the same gains as Maxwell who includes the weak force in his calculations for absolute accuracy. Remember what I have told you " A radiator can be any size, shape or elevation as long as it is in equilibrium" This is contrary to what the experts say that a radiator MUST be straight, which is absurd. But then you rely on absurdities. Your friend Art |

David, you just have to be a leader in this. Total reliance on books or even on wilkapedia is for the birdes. It is upto you what rock you build your reputation on. Going to school only brings you up to date with other peoples thinking so that when you leave you don't have to reinvent the wheel. For the increasing number of head woblers that are join ing the hobby that is understandable but for those who sought education as a means of just making money is really stealing from the next generation. Education is meant for the advancement of the human race where continued scientific approaches after school was meant to correct the errors of the past to strengthen the rock for the next generation to build upon. Denial of progress or the effort to prevent change is just theft so that the children have to follow the selfish efforts of their elders. Change will come with respect to antennas tho probably after you have gone. You may posses the direction at the present time of a generation but soon you will be gone and the human spirit formerly chained by their elders will re emerge in disbelief of their elders folly who while dwelling in a garbage can felt safe from intruders, learned to ignore the smell that became associated with them feeling that they had won the conquest of change prevention Your final place of rest will be in a hill amoung friends but without a voice.

Art While visiting a cemetery in Smog Angeles, I saw several monuments that included a recording of the deceased saying a few last words. Push the button and it plays the recording. That was many years ago, and I suspect they've gotten better with video clips and LCD displays. Maybe the next step will be a 3d hologram. You may be dead, but you can still annoy the relatives. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

So what is available today for hams in the HF BANDS? There are a lot of older type audio S A s on E bay but I haven't heard of anybody modifying thoseand with most having computors it would seem reasonable to think that there were components available that could performn between audi and 2.4 Ghz. So has anybody seen any modern type DIY spectrum analysers around for sale or kits? I have 141t and other types of SA which now are considered bulky and I would really like something smaller or say modify something like a audio setup as a project. Comments To work with an SA on antennas you will need either a "noise generator" (modern method) or a tracking generator (old method) which can control the SA. better go for a scalar analyzer or if you can afford it, get a vector analyzer w. |
