An inverted-L antenna can be converted to a T-antenna just by sliding the
vertical wire from the end of the L to the centre of the T. At intermediate
positions we get the original Windom antenna.

The small difference in configuration between the two is unlikely to have
much of an effect on signal to noise ratio.

The T behaves more like a true vertical than the L. It is well known the
vertical is a low-angle receiving antenna and therefore picks up more
locally generated noise.

So if there *IS* any difference between the two then it will be in favour of
your existing inverted-L.

The local noise environment, ie., where the noise is coming from, will also
have an effect at least as great changing the wire configuration. But not
very much.

(By the way, the lengths of the T-antenna wires are non-critical. The
bottom-end loading coil can be dispensed with and incorporated in the tuner
if the tuner has sufficient inductance.)

I seen in a recent article showing a Compact T Antenna for 160 Meters.

Tophat is 80 ft long and the T is connected in the center and should be
40ft
long with a 20uH to the feedpoint then the shield to ground.

Has anyone used one of these antennas? I use a Inverted L right now and
it
is playing very well but the noise is S9 to 5 Over. I understand the the
T
Antenna is a much more quiet antenna?

Thanks
