![]() "Cecil Moore" wrote Reg, a standing recommendation of mine is to download the free demo version of EZNEC and have fun learning how to use it. Any amateur radio operator who succeeds in doing so will be rewarded for the effort expended (and was also a source of extreme pleasure in my case). ELNEC/EZNEC and the Smith Chart (Microsmith) are the most useful tools I have ever encountered for comprehension of antenna systems. (Not considering reference books as "tools".) -- =================================== Dear Cec, In the present context, in the absence of body language, your praise of EZNEC can perhaps be misconstrued as my criticism of that erstwhile computer program. On the contrary, I quite agree with your comments. Regarding the Smith Chart, I have myself never found it to be of any use. In fact I don't know how to use it. I am aware of its long-standing existence, and what it is purported to achieve, from this newsgroup and from the one or two ancient 'bibles' which I seldom refer to. But the absence of a Smith Chart may be due to some vague shortcoming in my education for which I have no responsibility. So I have never felt myself to be handicapped in any way. Indeed, I have gained from this and other websites the impression that I am considered to be a transmission line 'expert'. But I claim only to be a well-educated, useful engineer who also happens, in retirement, to be a radio amateur with the ability to express myself in plain written English. To continue with my earlier message, I have just finished a third glass of white, South African wine. But enough about me. What are you doing about Bush? ---- Reg. |
