Hi Mikeladd, the thread address you uploaded does not work, pse check, thank

HI Mike, Your experience is very informative and clearly shows the risks and pitfalls in circuit design. Reliability analysis, based on MIL specs, was done in the company I was working for several years and the most difficult process was that of finding an optimum balance between component count and...

Hi glovisol, I agree with Mike that two series capacitors are needed to avoid the danger of shorting the bias voltage. I also note that with the circuit as is now the antenna common lead is shorted to the 12 V supply common lead and this could bring noise in. It would be advisable to put a choke in ...

Hi Tech_Support, I am glad you have eliminated posts with controversial arguments that do nothing but creating confusion and ill feelings among forum members. With sincere appreciation,

Thomas

Thanks to Mike and to RSP2user for the information and also kudos for very impressive images!

Mike, it seems to me that your filter is low pass filter, e.g. suppresses MW & higher band to let you get the LW band. I am under the impression, .maybe I am wrong, that Franko wants a high pass filter, to suppress MW in order to listen to HF from 1.9 MHz & higher, as shown by glovisol.

Hi Phil & Gianfranco, it seems to me that this thread, that had to be closed, because it had become "toxic" according to some guys, is by contrast showing a lot of useful information on small antennas. This is a lesson to us all that a good discussion on technical problems and data is only "toxic" f...

What antenna are you using? Nice images!

Phil,

Thanks a lot for your help & guidance. I am studying the references, got a lot to learn in practical antennaship & will get back to you when stronger on my legs. Seems glovisol is having a ball with your concepts!

LNA gain depends on noise level of your antenna. Get a signal and then adjust for best S/N.
For mouse you should go to the mouse controller & change settings.
