JK, RC and CM,
I suspect that may be one reason that this Far-End Loaded AM/MW
Coil may work is the fact that the RF Systems EMF Antenna is
'only' Sixteen Feet (16') Long; and the Two Inch to Three Inch
(2"-3") Ferrite Rod at the End of the Wire Antenna Element does
have some 'measurable effect' on improving the AM/MW Frequency
Band performance of such a short Antenna.


Yes, I was assuming you had a short antenna and wanted to load
it. The reason for loading a short antenna is to increase its
electrical length closer to resonance and the benefits are much
more pronounced for transmitted signals. Most modern HF receivers
have enough gain to make up for a less than optimum antenna.

Loading a long wire antenna doesn't make much sense.



CM,

A 100 Foot long Inverted "L" Antenna is not a Long Wire for the
AM/MW Broadcast Band with coverage for 530 kHz to 1700 kHz

* One Wave Length for 530 kHz is 1896 Feet; and 100 Feet at
530 kHz would only be 0.053 WL.

* One Wave Length for 1700 kHz is 591 Feet; and 100 Feet at
1700 kHz would be 0.169 WL.

Like most people I do not have 600 to 1900 feet of space to
string up a true "Long Wire" {One Wave Length} Antenna for
the AM/MW Broadcast Band. So this is why I am 'questioning'
the use of Ferrite Rod Antenna with a Coil as an integral part
of a 100 Foot long Inverted "L" Antenna.
