This is probably one of the most important posts we’ve had on this site. This is VERY cool. I have given Rich a bit of a rough time, taking him to task on simulations, but this is critcally important, hard data we can really use!!!
I’m glad you kept coming back for more, Rich, because this is gold. I had run some simulations on the[url=http://webpages.charter.net/crstrode/calcs/RFcalcs.htm] [size=12:ec84f45da3]WA7CS[/size:ec84f45da3][/url] site, and I kept getting .27 pecent efficiency, which seemed [i:ec84f45da3]way[/i:ec84f45da3] too high, and my sims indcated a Q of over 400 – also unlikely.
Rich’s work gives us a much more realistic target for our antenna tuning. I think many of us are probably getting around .09%, and it’s very encouraging to see that we might get as much as double that if we really try.
These efficiency percentages seem awful because, of course, they are – that’s why the FCC lets us do this 😀 but to have some accurately calculated goals is very helpful.
Also one of the best descriptions of the function of the loading coil I’ve seen on the ‘net – I might steal that for our library 😳
Thanks again Rich – glad you’re on board
