NOTE : For the sake of this discussion all Four of the
Inverted "L" Antenna Elements are co-aligned in the
same Vertical Plane.

- Why? You going to build this?

Just For The Fun Of It - To Try Something Different.
-ps- It is an Experiment !

--pps-- In Search of a Serendipity Moment.

- Well, it can't be built.

Now There You Are Clearly Wrong - IIRC a few People
have Attached separate Antenna Wires to each of
the four Antenna Terminals of the ICE 180 and had
good results.

The ICE 180 Matching Transformer has been used for :
Four Element Multi-Band 1/4 WL Vertical Antenna
Four Element Multi-Band 1/4 WL Horizontal Antenna
Four Element Multi-Band 1/4 WL Sloper Antenna
Four Element Multi-Band 1/4 WL Inverted "L" Antenna


TheICE180 Matching Transformer 'acts' as the Collection
Point for each of the Signals coming from the Four 'individual'
Wire Antenna Elements.

- Do you understand that these signals are vectors
- with magnitude and phase not just magnitude?

Teli - You make it sound soooo Scientific )

That is a rhetorical question don't answer it.

OK I Won't ;-}


In this instance the Four Taps on the Antenna Side of the
ICE180 Matching Transformer 'act' as a Summing Network.
The Output of which is fed {transferred} to the Coax Cable
Side of theICE180 Matching Transformer.

Each of the Wire Antenna Elements is 'separated' in Space.
15.1 Feet & 19.7 Feet & 24.5 Feet & 38.5 Feet
Deltas : 4.6 Feet & 4.8 Feet & 14 Feet = 23.4 Feet

Each of the Wire Antenna Elements is a 'different' Length
-wrt- Wave Length; and therefore 'unique' to itself.
39.6 Feet & 51.5 Feet & 63 Feet & 97.7 Feet

Collectively All of the Wire Antenna Elements add-up-to
More Wire In-the-Air and a Greater Signal Capture Area.

- Not necessarily.

Yes -if- It is done right.

More Wire In-the-Air :
39.6 Feet + 51.5 Feet + 63 Feet + 97.7 Feet = 251.8 Feet Long

Greater Signal Capture Area :
300 Tap "L" by itself : 15.1 x 24.5 / 2 = 185 Sq. Ft.
450 Tap "L" by itself : 19.7 x 31.8 / 2 = 313 Sq. Ft.
600 Tap "L" by itself : 24.5 x 38.5 / 2 = 472 Sq. Ft.
800 Tap *"L" by itself : 38.5 x 59.2 / 2 = 1140 Sq. Ft.
Collective Areas : 2110 Sq. Ft. filled with Four Wire Antenna
Elements versus anyone of *the single Elements.

- Where did this idea come from? It makes no sense.

The Signal Aperture {Physical Shape and Size} of an
Inverted "L" Antenna creating a Triangular segment
within a Vertical Plane existing in Space : All Things
Being Relative.

- The wire impedance is determined by its diameter and
- height above ground. This aspect of a single wire is
- independent of the frequency of operation but nearly
- any other aspect is dependent on frequency.

The Wire Impedance and Frequency are not the Issues :
They Are What They Are [.]

How the Four Wires are Connected to the ICE 180 and
collectively How the Four Wires Act as a Composite is
The Experiment under consideration.

Summary :
All of this is not 'scientific' but simply a practical approach
to puting : More Wire In-the-Air by using a specific feature
of theICE180 Matching Transfromer : The Taps.

- It doesn't work that way.

So Say You.

- You could add a wire to another and have less
- signal or more signal.

Usually More Wire In-the-Air -means- More Signal.

yes - i know that 'in-theory' i am wrong
-but- practically speaking i am . . .
sort-of kind-of right - iane ~RHF
*.

- No you are just wrong.

That's your 'opinion' and I do not Share It.
