[Lowfer] Return of loop testing at 185.3

Thu, 27 Feb 2003 17:16:46 -0600

Like Lyle??? He has plenty of room for a loop in any direction or for that
matter several loops in several different headings. How 'bout installing a
test loop Lyle??? I will stop up and help if you like as long as it is
before the mosquitoes and wood ticks come out.

Eric,

I've thought about doing this from time to time so as to re-validate the
improved performance of the loop over the vertical at this location. Using
the big loop as a reference signal would really show the difference. I still
have the Litz loading coil and I don't believe it would take too long to
install the top hat and other parts of the system. I'd have to be real
careful to keep the antenna current constant and this used to vary with
temperature up to 2.5x (8db) on a single cold night! The sap content in all
the trees surrounding the antenna was the the only logical explanation for
this much variation.

>Would anyone else be interested in seeing this?

Just about the whole Lowfer community would be interested. I've been hoping
someone with more open space for good vertical performance would take this
on.
