AI Thread Summary
In hilly areas, FM radio reception can be significantly hindered, and users often find that proximity to their active antenna improves signal strength. The human body acts as a large capacitor, enhancing the antenna's performance through a phenomenon known as "touch capacitance." This effect occurs when a person stands close to or touches the antenna, which can boost reception. Users are seeking alternative solutions to improve FM reception without resorting to large external antennas. Exploring different antenna designs or signal boosters may provide better reception options in challenging locations.

i live in a hilly location where i have very difficult radio reception, so i am always futzing around with my little "active" antenna for FM radio (PBS). i notice that reception always improves as i move near the antenna (like within 3-5 feet is noticeable), and gets much better if i just touch the antenna box.

what is it about the human body that would improve the antenna operation? and how can i make the stupid antenna work better without having to stand there touching it? other than installing some monstrous physical antenna on my roof, is there any other way to get decent FM reception in a poor location? thanks.

You are a large capacitor.
 
mommy! JD called me a big capacitor! make him take it back!

Could you elaborate on how that improves signal reception?

What is your body-shape type? Are you pear, hourglass or parabolic-dish?
 
That's all I remember. Old radioheads call the effect "touch capacitance".

You are a lot larger than that antenna, right?
 
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...
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
