Hi Harry,

Great explanations. Thank you.

I will try to build your suggested antenna first chance I get. Will let you
know how it works out.
BTW: is this what's (also) called a "J Pole" ?

Should it be pointed in any specific manner toward the source of what you
are trying to receive ?
e.g.: should a plane formed from the short & long lengths be pointed to the
source ?

Q1: I have no idea how it's constructed, but what I describe as vertical,
the "tube" of the antenna is true up-down vertical.

Q2: Signal is "fairly" strong; it's only the noise that makes it hard to
listen to when held vertically in the normal manner. Much better
horizontally, and vertically downward, like I mentioned.

Are you sure that it is noise, is there some speech or music in the
"noise"? It could be an intermodulation product or just overload to
your receiver from a local FM broadcast station. See what happens
when you listen outside. when it is interference from your own
domestic equipment, the level should drop when outside your house.
Many so called "wide band receivers" give problems when used with a
good outdoor antenna.
