Set up the yagi in YO with the proper taper, and then save the yagi
design with the .ANT extension. This will cause YO to save it as an AO type file. That should get you a well along the way for your EZNEC entries. tom K0TAR sbc yahoo news wrote: For most part must agree with all, and REMEMBER, that these are NOT totally exact-- for instance- done same with (YE-GADS!) a 6 meter 7 element yagi, with pretty well known properties, by M-Squared, both in YO, and in EZNEC-- and the forward gain is more or less identicle, but the F/B is something else! However, didn't taper the elements (first 18 inchs at a given diameter, rest of el length, a smaller size tubeing-- does this make EZNEC an error prone program? NO! t'was my fault in NOT takeing the time to input all those extera connections into the model ! (tho, would be interesting to see it PROPERLY modeled, and admittedly, YO handles this much easier for a yagi- did the same for a DX engineering, (elements ALL same diameter) and forward gain is about the same and the f/b is within 5 db (the 7 elM squared is about 15 dB different F/B) But all in all, best to trust EZNEC- seems pretty much dead on for most applications. as info-- Jim NN7K And, PS, is nice to see a CIVIL conversation here! JF "Reg Edwards" wrote in message ... A very rare, welcomed, combination of events has occurred. First we have a sensible, concise, well-presented enquiry about inverted-V's. And secondly we have a response from Richard (Clark) which combines both his advanced (never doubted) technical knowledge and his ability (but long awaited) to express himself in the logical, unambiguous, easy-to-understand English language. Makes a change from the deliberately confusing, psychologicially mixed-up stuff we are accustomed to. Keep up the good work. But may I say I have learned a lot over the years from your own how-not-to-do-it mode of expressing yourself. Richard, please forgive me for being so forthright in public. I'm on Valencia red this evening. I'm sure you will understand. Incidentally, I think the English and American languages, after a generation's lapse, are coming back closer together again. You get rid of Bush and we'll get rid of Blair. --- Yours, Punchinello, G4FGQ. |
