Hi Roelof, LF,
=20
Roelof, why do you think that this is the case? Interesting Question! "Won=
't work" means "Won't work properly" it assume. There will be a signal but=
 perhaps it is not optimal. And why could this be the case? If the applica=
tion is in a metallic housing that is mounted to a metallic mast, the capa=
city of the "ground electrode" against the environment must be very high=
 (can be seen as infinite, i assume), compared to the active element (gate=
 of the FET). Perhaps there will also be a better coupling to qrm sources?=
 I also have to make some measurements. The antennas we use are comparale=
 i think. So we could share (all) share our experiences :-)
=20
A special question comes up when a optic fiber cable is used, since in a=
 coax application there remains a high C of the ground electrode, even whe=
n a symmetrical transformer is used (since the active element has just a=
 few pF to the far field). That special question is: What will happen, whe=
n the case/ground electrode becomes small against the active element (e.g.=
 circuit in SMD, small battery inside)?! Will there be a change in the opt=
imal C of the active element to the far field? I assume, then, one has to=
 define an optimal C ratio of both electrodes. Will it behave as a short=
 dipole? And what about a short vertical (30cm) active antenna that is dir=
ectly placed on the ground with a almost ideal conducting ground plane, e.=
g. aluminium foil (out of the household) in a radius of 1m (ignoring the=
 local qrm problem, so e.g. in your garden, apart from the city)?
=20
On my new qth i made first steps to receive LF with the active antenna mou=
nted just 2m above ground but hung up on a wet tree. Results were vy bad.=
 I thought that SNR could be better when increasing the active element sin=
ce signals were weak (DCF39 at S7), but it wasn't. The optimal length was=
 still 30cm. That seems not only to be "sufficient" but rather optimal! So=
 less and more is worse, unaffected by the hight above gnd?
=20
I think one has to imagine the E-Field lines that are going through the am=
bience. The fieldstrength seems just to be very small in a lossy environme=
nt (on my hill, where no trees can be found, the antenna was also 2m up an=
d DCF39 was S9+20). So hight above ground seems to essencial, even without=
 local qrm. Each decrease of input signal can be compensated by more gain=
 but SNR decreases, of course.
=20
What are your ideas to these thoughts? What do you think will happen if th=
e ground-electrode-C becomes small against the C of the active element? Wh=
at will be the optimum C for both? Will the electrodes have the same "impo=
rtance", like as a short dipole? Questions over Questions ;-)=20
=20
Recently i had the idea to test that with a variable antenna of a /p UKW=
 radio, perhaps two for each electrode. That will be interesting to play=
 with ;-)
=20
73!! Stefan/DK7FC

Hello Stefan,

Probably a bit late, bit I have been told that an active whip won't work=
=20
well on a metalic mast.
I never tried it myself (still on the to do list) due to lack of a=20
suitable mast.

73,
Roelof, pa0rdt
