Thank you...for a big guess on my end - I guess I owe an apology but too, looking over this the only error I see in my wording if from the 72 PRESUMED - it should have been more 50 ohms - but taking a look at the internals I can also understand why this thing just "radiates" in the down lead of coax too...

Now in the article, he mentions dBi - which is gain over Isotropic. I'm not even going to go there, it's in the realm of Dummy loads.


But I do see the correlation of 1/4 wave wound coil and it's impedance to run against - parallel to, the 1/2 Wave length radiator - the Capacitor assembly or the overall assembly - wow - you just can't make this stuff up.
