The power of the signal would be high or low if you are transmitting in omnidirection antenna as compared to directional antenna?
The power of the signal, as perceived by the receiver, will be lower with an omnidirectional antenna. This is because the omnidirectional antenna is transmitting in all directions, while the directional antenna is transmitting in only one direction.Think of the directional antenna as a lens, focusing proportionally more power in a smaller space.
Is parasitic elements are used in yagi-uda antenna?
Yes - reflector element and directional elements.
Why yagi uda antenna is used?
Some advantages of the Yagi- Uda Antenna include that this is a widely used design and low cost. The construction also is simple. Some disadvantages are that the receiver of the Yagi-Uda Antenna may have problem receiving signal.
Why aircraft vhf antennas are polatised vertically?
Aircraft can approach an antenna from any direction, so antennas need to be omni ("all") directional in the horizontal plane. Early on, the easiest way to get omnidirectionality was to use vertical polarisation, and it's also the simplest kind of antenna - a simple rod or wire (of the right length) works just fine. Subsequent antenna design has produced omnidirectional antennas with horizontal polarisation, but there are no significant advantages, and the design/construction is more complex than a vertical equivalent.
Are resistors directional?
no

What type of antenna using in mobil bug?
omni directional antennas
Can you use a TV antenna for a remote control helicopter antenna?
If the TV antenna was built for the correct frequency, it would work but my second thought is do you want the antenna to send a directional signal? I would think a "omni" signal (all direction pattern) would be a better choice. Most TV antennas are directional.
What is a Yagi-Uda antenna?
how to measure the length of elements and spacing of elements
What is a directional antenna in a LAN?
Directional antennas work a bit like the reflectors behing the bulbs in flashlights, shaping the beam to go mostly in one direction. You get better performance that way, assuming you can keep the antenna pointing in the right way.
Advantages of omni directional antenna?
can transmit in all directions with a donut shaped radiation pattern.
