    Yes, if the signal is strong enough there should be no problem.
    If it's a weak signal then you might have to use a dielectric plate inserted in your lnb.

    The feed system (Teflon) provides simultaneous RHCP and LHCP reception. In this case, V stands for RHCP and H for LHCP.

    I already tested the same but failed as in BANGALORE we face Signal Interference so due to signal flashing I was not able to get signal.

    When tried with L & R feed signal was constant

    You can use a single lnb with H/V (18V/13V) polarity then you can watch all of the channels

    Insert Dielectric Slab in feedhorn about -45 or +45 degrees depending on whether
    the signal is left or right circular.

    @YAN actually what Anish told is correct if the Sstellite Signal is strong may be we can get with C BAND DUAL POlarity LNBF.

    EXPRESS AM2 @80 degree is very very strong satellite.

    So that why I think you got both L/R with same LNBF.

    I tested on YAMAL 202 that is strong only in MAP buy practically not such strong as EXPRESS.

    I was able to get L polarity around 75% but R was only 30 %

    Yes brother , it's true . Yamal 202 is edge of my region and i got very low signal . Nowadays it more harder to get the signal form Yamal 202.That's show we can't get L/R signal easily with dual polarity LNBF. How about Telfon n did u try it ?


    Thx.

    YAN I DIDNT received both L & R using DUAL LNBF.

    I got either L or R using L or R feedhorn. Using Teflon also I get Either L or R.

    But in Northen part of INDIA where all russian satellites have very good signal there even we get signal without inserting TEFLON.

    If we make Center focus Thaicom 78.5 Degree we also get EXPRESS AM2 without inserting TEFLON

    Wow ! Nice on there but in here Express Am is very difficult to get that signal.
