Lab #2 Part 1, Antennas

Lab Report

Omni- directional

Let’s look at an Omni-directional antenna example: Think of the ripple that is created when a person throws a stone in the middle of a calm body of water (such as a pond). As the rock enters the water it causes the water all around it to rise and creates a ripple in the water.

• Think of this ripple as the “WAVE”.

• Think of the “FREQUENCY” as the number of the waves or the occurrences where the wave repeats over a period of time (from the stone to the shore).

• Think of the size in height of the wave as the “AMPLITUDE”, and

• Think of the length of the wave as the “WAVELENGTH”.

• As this wave moves outward away from the rock’s point of entry and towards the shore, the migration of this wave is called “PROPAGATION”.

Omni directional antennas are used to receive TV broadcast signals from all directions, rather than a directional antenna that receives signal from one direction. You can install an amplifier to boost the signal from the Omni directional antenna if you are getting weak reception from the antenna due to a large amount of wiring in between the antenna and your TV. Amplifiers are not a cure-all for antenna issues as they can increase distortion.
