Hello Peter,
Thanks for the link, very interesting and relating to the current
discussion :-) I expect many of us are reading the dissertation right
now ;-)
Especially fig. 5-16 on page 139 is interesting. Downscaling to a µr of
400 (in my case) is required but anyway the trend/dependency is useful
to see.
Anyway, both, the diameter and length is useful to improve the SNR. But
for my /p antenna, making the rod much longer than it currently is (=28
cm) makes not much sense if the goal is an antenna that can be carried
in a backpack. Once it becomes 1 m and longer, a simple single turn loop
could be used as well...
Going on reading now :-)

Hi,
O.K., once again. Seems like to post into /dev/null...
