    Antenna Size Calculation:

    Well as as simple rule longer the hop, bigger the antenna and lower is the frequency.

    But to decide the MW antena size you need to know the amount of average rain in the area,Reliability requirement, Fade margin demanded by customer and the properties of the Specific Antennas.

    Please getting concept is a key to success.Given a new technology or new equipment such as SDH,PDH,MINLINK,ALCATEL DMR etc.Assume all these are quite new to you,and you want to be as good as you can in playing with them.How can you start.I welcome anyone to volunteer and this will be a key to those who need to understand RBS 2206 etc.Waiting for youu guys.Thanks

    1) why is -ve voltage used in the bts or RBS 2204.
    2) how does the grounding help the system.

    check TX Power.

    If all it’s correct, you have probably an ODU HS.

    Thx Patrick for response but it would be to easy. Tx power is max on both sites (23dBm) and capasity settings are the same.. I don’t belive that antennas are not panned corectly. I think there would be bad Rx level on both sites in this case.The same with Rg cable damages or wrong polarization….. What else can it be?
