Some areas in North and Central Africa : min. 450-700+ cm > possible spectral identification carriers at the bottom
and the top of the KU band but only with the unstable level of gain margin in the range of MER=1 to 2 dB in parts of
the spectrum from 10 950 to 11 200 MHz in the horizontal polarization,mainly in the evening.

NSS 6 at 95.0°E-packet Dish TV DTH : author's research activities in the field of wave physics
.
After more than five years of research work in the reception wave of NSS 6 with the elevation angle of only one degree
above zero, which falls into the category of wave physics, I come to a result which completely deny my initial conclusions
on the direct relationship between the size of the elevation angle and the presence of continuously oscillating signal
levels in a wide amplitude range, which I was associated with the reflector antenna noise temperature and noise
temperature of the earth etc. My calculations would confirm the high quality factor antenna, which I derived from the
ratio of G / T, that is based on a theoretical perspective should be final quality of earnings during an elevation angle
of only one degree less significantly degraded as I identified in measurements in recent years research activities.
So I am not able to put into action a high quality factor antenna derived from the ratio of G / T, which is in this type
of antenna with nearly ideal ratio f / D (0.37 vs 0.4) significantly less degraded antenna noise temperature factor.
A turning point in my research activities took place six months ago when I understood the direct relationship between
the position sensors waves in waveguides and permanent oscillation, which significantly degraded the quality of
reception from the orbital position 95° E.
Then I understood and applied this change in the waveguide,permanent oscillation of all transponders in India and
the Middle East footprint reduced by 75%, as evidenced by the quality of video records of reception for different
transponders from India footprint.Periods with stable detection of the carrier in the Indian spot was significantly
prolonged and specifically in the HD transponder at f = 12 647 V I have identified a stretch of 45 minutes without
pixelation and downtime .
