Dipole Antennas: The Simplest, Most Common Antenna
As it's name suggests, in its basic form, a dipole antenna consists of two conductive elements, unlike a monopole antenna, which has a single conductive element. The dipole's identical conductive elements (usually rods or metal wires) sit on either end of the antenna.

No. A half wave dipole has a low input impedance. A center-fed full wave antenna will have a very high input impedance and will require a matching network between it and the feedline or transmitter. A half-wave antenna is a complete, fundamental radiator, and is the basic resonant length.

What's the best overall TV antenna? The best indoor antenna, based on dozens of CNET's tests, is the Mohu Leaf. It gathered the most stations in two different locations, and it can be yours for $35. Its sibling the Mohu Gateway was also a strong performer, and it has the advantage of tabletop use.
Are flat antennas better?
It depends what you need the antenna to do. If you want a “surveillance” function, then you want the antenna to see in all directions; such antennas necessarily have low gain/low dBi. On the otherhand, if you want your antenna to “stare” in a very limited direction, then high gain/high dBi is appropriate.
Is antenna better than cable?
So, a 3dB antenna has the same gain as a 5 dBi antenna. There is no performance difference between the two antennae. It is just the way that each vendor chose to specify each antenna.
What antenna gives you more channels?
Parabolic dish/grid antennas are well known highly directional antennas.
Is a higher dBi antenna better?
Directionality: Antenna shape can also affect the directionality of the antenna, which refers to the direction in which the antenna is most sensitive to radio signals.
Which is better 3dbi or 5dbi?
Antennas rely on size to be effective. This includes their height and length. However, bigger isn't necessarily better. For example, taller antennas don't always have greater range than shorter ones.
What is the most directional antenna?
You also want the antenna to be at least 1/4 wavelength long for each band you plan to use. For instance, to work 40m be sure the antenna is at least 10m or 33' long.

Place the antenna in or near a window
The fewer obstructions between your antenna and the broadcast towers, the better. And make no mistake–thick walls and ceilings are certainly obstructions. That's why placing your antenna in or near a window often yields the best results.
Does antenna height matter?
Another approach would be to focus on the radiation pattern. Changing the aperture of a dipole or stacking multiple dipoles changes the pattern shape, directing existing power to where it will be used. Tuning the antenna can be accomplished without requiring hardware changes.
