We were re-aiming the directional antennas and checking with a spectrum
analyzer. Our test was perfunctory yes and we gave up after only four
sites much to the surprise of our S. Korean LG friends who expected at
least two grueling days.
The fact is that in Richard Bogner's bedroom looking out his window at
solid green and very tall and thick trees that were waving in a moderate
breeze the simple loop and rectangular antennas casually taped to a
window were only matched by his rotored and very substantial and
complicated rooftop antenna.
That rooftop antenna only was able to match the two wire antennas with
the use of the rotor.
Why, we asked Mr. Hong and Mr. Koo, should we go on, this receiver works.
They are touring Manhattan today.
