Antenna

AI Thread Summary

Antenna reception can be significantly impacted by the presence and movement of a person in the room. This effect occurs because the wavelengths of TV signals are similar in size to the human body and limbs. UHF frequencies range from 10 cm to 1 m, while VHF frequencies range from 1 to 10 m, making the human body a potential obstacle or interference source. Even slight movements, such as swaying an arm, can disrupt the signal. Understanding this interaction can help optimize antenna placement for better reception.

I have a antenna in my room & it runs to my tv tuner.

Just curious why the reception of the signal is affected by a person moving around the room? Even swaying your arm slightly affects it.

thanks.

reckon

because the wavelength of tv antenna is in the same order of magnitude with your hand.
A UHF frequency have wavelength between 10 cm to 1m while VHF frequency have wavelength between 1 to 10 m. [data taken from Wikipedia]

Hope it explains

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Linear generator prototype'

i want to just test a linear generator with galvanometer , the magnet is N28 and the wire (Cu) is of 0.6mm thikness and 10m long , but galvanometer dont show anthing , The core is PLA material (3d printed) The magnet size if 28mm * 10mm * 5mm

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
