Have any of the antenna guru's figured out that the color burst 
frequency of a TV is
3.579545 MHz?

color burst: In analog color television 
<http://www.atis.org/tg2k/_television.html> technology, a signal 
<http://www.atis.org/tg2k/_signal.html> consisting of several (8 to 10 
in NTSC) cycles of unmodulated
color subcarrier <http://www.atis.org/tg2k/_color_subcarrier.html>, 
superimposed at a specified location within the composite signal. Note: 
The color burst <http://www.atis.org/tg2k/_burst.html> (a) enables the 
color-decoding
circuits in the receiver <http://www.atis.org/tg2k/_receiver.html>, and 
(b) serves as an amplitude, frequency 
<http://www.atis.org/tg2k/_frequency.html>, and phase 
<http://www.atis.org/tg2k/_phase.html> reference to which the local 
color (subcarrier frequency)
oscillator <http://www.atis.org/tg2k/_oscillator.html> in the receiver 
is phase-locked to ensure color fidelity 
<http://www.atis.org/tg2k/_fidelity.html> and stability 
<http://www.atis.org/tg2k/_stability.html> in the displayed picture 
<http://www.atis.org/tg2k/_picture.html>.

If Buck is changing the color of the TV on every frequency he operates 
on, then he's getting into the IF and affecting the
color burst.

However, that says that not all of his power is going to his antenna and 
up the tower.
