    It is MHz, not mhz. Why is this you might wonder? Hertz is abbreviated to Hz to begin with. Mega = M, Giga = G, Tera = T, hence MHz (10^6 Hz), GHz (10^9 Hz), THz (10^12 Hz). There's also milli = m (10-3), micro = u (10-6) and nano = n (10-9), so 1.3mHz would be 1.3 milli hertz, that's 1.3/1000=0.0013Hz.

    Also, there's no 1.3mhz transmitters, there however are 1.3GHz transmitters, please make an effort to get the nomenclature right! Thank you!

    Do you know if you can make an antenna that will go 200km on 1.3GHz? Might be something I'm looking at as I have to change my video freq.

    Already done (but not tested yet...):

    He discontinued the 1.2ghz heliaxial antenna due to a few different reasons. Theres a thread about it here somewhere, probably in his corner of the sponsors gate forum area.
    Far better is it to dare mighty things, even though checkered by failure; than to take rank with those who neither enjoy much or suffer much, because they live in the gray twilight that knows not victory nor defeat.

    Thanks guys. This week-end (finally...!!!) they will become available again in our website. Some issues with the aluminum cutting machine have delayed us 3 weeks...
