      current status in EIRP levels in East European area : Prevailing local reception disparity in quality in terms of choice
                                                                        of the V or H vector

- in case of receiving satellite Astra 2D in East European level, I can define the following an elementary rule : without
the initial measurements at the antenna installation is not possible to correctly define (with a high degree of probability) the
required diameter antenna to a stable reception of a TP in the plane waves H or V .

- the smallest antenna diameters for unstable carrier lock (in units of minutes to hours), depending on the geographical location
of the antenna installation location in Eastern Europe :

                                             --- for packets broadcast in vertical polarization ---
in my point measurements : unstable from Dmin=140 cm and stable from Dmin=220-240 cm ( V pol sidelobe )
in other Eastern European reception areas : Dmin=90-270 cm

                                             --- for packets broadcast in horizontal polarization ---
in my point measurements : unstable from Dmin=340 cm ....and stable form of reception for all TP from Dmin=???
in other Eastern European reception areas : Dmin=180-500 cm

10 847 V : constellation analysis with only a slight disturbance which reflects the status of almost perfect quality
(ChBER<=6x10-6), which I cyclically identified in measurements of the transponder TP 50 in the timeframe from 12 to
13 hours,at reception point Lučenec-Slovakia . / PF 3.7 m

10 847 V :
just in time frame from 12 to 13.00 pm I identify quality peaks on transponder TP 50, which is reflected a
cyclical downturn on the channel BER at levels equal to or approaching zero,with the MER values ranging from 13.4 to 14 dB.
