[Lowfer] Loop Antennas for Transmitting

Wed, 7 Aug 2002 21:02:57 -0500

I don't know, but it was an interesting project to put together. My
neighbors don't even know it is there. I used black insulated wire and it
disappears against the woods. I do have to tell you guys this; this loop and
the LF band with the support of all you people on the reflector has gotten
me interested in the radio experimenting once again. My rigs usually sat
around for a few years between QSO's. I even wore out one of my Weller tips
on this project. Hi Hi.

At 185k the radiation resistance is about 100 times lower compared to a
vertical of equal size, and this is a bad characteristic. So the current
in
the loop has to be 10 times higher to make up for this....  and this is
doable if you understand how to deal with the variables..... and they are

quite different than those for a vertical. In fact the loop is far less
susceptible to outside forces and is much easier to install.  .....and
far
less unsightly, if not invisible.
======================================================

and you dont want to forget the pattern which gives some improvement
in signal in the favored direction
( I didnt say gain )  Grin

and if judging by Mikes enthusiasm must be addicting, could loops become
a controlled substance
