Thank you for your replies and now I I understand the difference
between the Yagi Antenna and LPDA Antenna. But that is not
the focus of my questions :

A Few FM and TV Antenna Questions {Clarifications}

I have seen two general types of Multi-Element FM & TV Antennas :

1 - The most common is the Multi-Element FM & TV Antenna
with "Flat" Straight-Line Elements.

2 - The less common is the Multi-Element FM & TV Antenna with
slightly "Bent" Canted "Vee" - about 15 Degress Elements.
The Tips of the Elements pointed slightly to the Front of the
Antenna. See the Log Periodic Dipole Array (LPDA) Image

OK - I understand the difference between the Yagi and
LPDA Antennas.

MY QUESTION IS :
What does the "Canting" {Slight 'Vee' Shape Bent} of the
Antenna Elements Do ?

? Does it Broaden the Angle of Reception {Capture Area}
of the Antenna over the "Flat" Straight-Line Elements ?

? -Or- Does it Narrow the Angle of Reception {Capture Area}
of the Antenna over the "Flat" Straight-Line Elements ?

? What about Front to Back (F2B) vice Side Signal Reception ?
* "Flat" Straight-Line Elements -vice "Canted" Elements
? Which has the better Front and less Side Reception ?
? Which has the good Front and fair Side Reception ?

The common Multi-Element FM & TV Antenna which has "Flat"
Straight-Line Elements.

# 1 - When mounted Horizontal "Flat" is very Directional
with a good Front-to-Back Signal and very good attenuation
of the Side Signals.

# 2 -IF- It is mounted Vertical {With the Tips Up-and-Down}
it is still some what Directional with a good Front-to-Back
Signal and now has fair Side Signals making it closer to
an Omni-Directional Antenna still with some Attenuation of
the Signals coming from the back-end.
* A "Cardioid" {Heart-Shaped} Antenna Reception Pattern

MY QUESTION IS : Are Both # 1 and # 2 Correct ?
- - - If Not - Why Not ?

NOTE - OK not about Shortwave -but- It is about Antennas.
