Here is one in a series of youtubes I did on pulsing coils that may show some of your effects. At 1.2mhz, one wire lighting of LED is common.

I once held the pulse generator terminals with my fingers and a coil with an LED lit up 5 feet away from me. I never was able to re-do the effect. It was the weirdest thing ever.

Please concentrate on that what I say here. It is important to do not waste your time or to properly isolate known science art from unknown science art.
Nothing special and nothing unusual I have seen on that video.
1.Every LC parallel or series resonant circuit is RLC circuit
2.Every coil, capacitor and most of resistors are RLC series and parallel resonant circuits at the same very time.... even if not connected to any other R or L or C and represent single electronic element of R or L or C.
3. Every coil, capacitor or most of the resistors have their own self resonant frequencies!!!!!
4. Every coil, capacitor or most of the resistors is resonating in self resonant frequency.. of
-series equivalent resonant circuit,
-parallel equivalent resonant circuit,
-combination of series, parallel resonant circuit . AT THE SAME VERY TIME !!!
BUT....
each one of self resonant frequencies is different.
each harmonic of that particular self resonant frequencies is fed by energy of primary resonant frequency.
5. series resonant circuit "wants to" blockade every frequency other than main self resonant frequency allowing maximum of amplitude only at that frequency
6.parallel resonant circuit "wants to" blockade only one frequency and all of other frequencies are allowed to pass.
What is filter and how it differs from resonant circuit.
The answer is: IT IS NOT DIFFERING AT ALL.
Coil or capacitor or most of resistors can be a filter even is it is not connected to any other R or L or C.
What is counterpoise of an antenna:?
It is a BALANCE to main or primary of active resonating element.
example- every antenna must obey laws of conservation energy
"Dipol antenna " placed horizontally looks like this
http://en.wikipedia.org/wiki/Dipole_antennaSay in the positive part of sign wave left arm is active and right arm is counterpoise -at that particular very time.
Vertical antenna ( say your car radio antenna ) weep is active and body of your car is counterpoise. (For HF frequencies is not that easy..)
LW antenna ( Long wire) is a single end of wire connected to TX ( transmitter or generator)
generator body is than counterpoise to the antenna.
But overall length of the wire must be able to resonate at frequency of choice, and additional tuning coil( and/or resonant circuit RLC) might be required to adjust counterpoise ( body of generator- metal box ) so the counterpoise becomes
balanceto that active wire and represents electrically equal balance to the active element.
Got the picture?
You just playing with antennas.
One of them is connected to transmitter - generator
Second one is connected to receiver LED.

PS:
Efficiency of an antenna:
If your "dipole" type of antenna is 40m long it will be 1/2 of 80m wave=3.8 MHz That antenna will resonate at 3.5 MHz. and take most of your roof and back yard length.
Now - You take this antenna and coil the wires
This antenna will than be on your table small and convenient and it will be theoretically the same exactly antenna .
but there is the catch!!!
efficiency of that antenna a will be very small.
That is why you guys are trying to connect straight wire to the radio to have better reception of the radio wave.
every antenna can be used as transmitting and receiving antenna .
some of car antennas have small coil at the bottom or in the middle.- that is for being able to keep electrical length of antenna and at the same time have height of that antenna smaller so it will become convenient in every day driving.
BUT IF YOU STRAIGHTEN THAT COIL YOU WILL HAVE BETTER RECEPTION.!!!!!!!!!!!!!!!!!!!
Although there is one catch:
The capacitive component of that coil is part of resonant circuit, so when you pull that wire and the coil become straighten than electrical length of that wire my push it to resonate at different frequency than previously designed.
Also bandwidth of that antenna will become more narrow.
In general for FM radio this is not important. That antenna is broad band FM antenna with unacceptable parameters for professional.
You can as well put piece of wire instead of THAT ANTENNA AND WILL WORK AS WELL.
And the reason for it is the signal strength is so big that many times you could put just one centimeter of wire and you will still be able to receive something.
That is what you doing now my friend.. just playing with known art.
http://en.wikipedia.org/wiki/Random_wire_antenna Is it worth of your time..?
YES it is..
It is like trying to trying to open the door with your nos...You may experience something that others will never find out.And that may lead you to discover elements of mechanism of your nos playing with the handle.
Rest of the world decided to be uneducated in this area or simply never thought about it.
But if you try to open the door that is already open than you have to create imaginary door. That leads you to graphics and art of graphics.
There is no motion that does not bring you to interaction and evaluation of that interaction..(within area of your 6 senses)
However there is ignorance to factors of interaction qualified as non important
