Martin,

I am glad hearing a Man's Talk.
In your induced method of measurement S21 of active loop antenna there is a need? to substruct? analythically from the total measured S21 the gain of passive transmitting antenna and the coupling loss between both antennae ( both factors are frequency dependant ) besides the mentioned physical inconviniences such as antennae orientation and proximity.?
I decided during the week to publish/reiterate any pertaining info for our community of professionals and amateurs about my approach to this issue by usage of signal injection method constructing a dummy aerial.
Then, I guess, we may open a forum of Q&A.
