Hello CW,

YES, for a Classic "Longwire" Antenna, sizing is about the 'length' of
the Horizontal Wire.

BUT - The subject here is an Inverted "L" Antenna that would NOT be a
'random wire antenna'.

So the first consideration would be maintaining the Shape (aspect
radio) of the Inverted "L" Antenna.

Then the second consideration would be sizing the Inverted "L" Antenna
to be resonte at a given frequency (SW Band) for some one who had a
specific interest in that band.

One simple method would have been to suggest making the total length
of the Inverted "L" Antenna one wavelength for that band:
EXAMPLES: Total Length equals Vertical plus Horizonal Sections
49M Band = 165Ft Total
41M Band = 137Ft Total
31M Band = 104Ft Total
25M Band = 85Ft Total
22M Band = 73Ft Total
19M Band = 65Ft Total
16M Band = 57Ft Total

A better method would have been to suggest making the TOP Section of
the Inverted "L" Antenna One Wavelength and the END Section of the
Inverted "L" Antenna a Half Wavelength. Thereby maintaining the
Inverted "L" Antennas Aspect Radio of 2H:1V (Shape Factor).
NOTE: This better method is what I choose to describe in my prior
post.

EXAMPLES: "L" Section Lengths for Horizontal and Vertical.
49M Band = 165Ft Horizontal & 83Ft Vertical
41M Band = 137Ft Horizontal & 68Ft Vertical
31M Band = 104Ft Horizontal & 52Ft Vertical
25M Band = 85Ft Horizontal & 42Ft Vertical
22M Band = 73Ft Horizontal & 37Ft Vertical
19M Band = 65Ft Horizontal & 33Ft Vertical
16M Band = 57Ft Horizontal & 28Ft Vertical

Better look up long wire. Verticle length has nothing to do with it.

If, by 'design' for a specific band of frequencies an Inverted "L"
Antenna has the Horizontal Top Section equal to One Wavelength and a
Vertical End Section equal to One Half Wavelength; then it would be
considered a Longwire Antenna for that Band.
