  1. Hi Folks! So I did my own SMA antenna mod on my Sennheiser G3 receivers. And I said, ok, If they now have the sma plugs, it might be a good idea to have and external LPDA antenna to then, so this way I could have all my rx on my cart, and have then with longer range! So I bough a rf passive splitter from 1 in to 2 outputs, and 2 passive splitter with 1 in to 4 outputs, this way I could send 1 antenna signal to 8 rx. I bought a LPDA printed antenna which claims to have 18dB of gain. To compensate for rf loss on the passive splitters, I also bought a chinese RF amplifier circuit with more 20dB of gain. As I knew all this amplification this could overload the receivers, in the other hand, I bought a variable resistor, which went just after the RF amp circuit, before the passive distro circuits. This way I could turn down amplification before overloading my receivers, by checking effective RF gain in the receivers screens. It did worked, in one side! I did have a strong signal with all my rx in my cart, the boost was very visible when I did power on the RF circuit amp! Great! But there is one problem - everything is going fine, and suddenly rf signal drops in intensity violently, and audio is lost. I couldn't find out if this was external interference or an internal problem with my system - maybe it is overloading rf gain anyway. But the RF signal in the receivers looses intensity, it is not going up is going down! This became happening very frequently, so I had to go back to my old system - to have my RX grouped on a tripod near the border of the set, and have a multicable bring audio to my cart. The old system proved more stable than the new one. Maybe I should try to have two sam antennas on each receiver - doubling this set up, so I could take advantage of the best signal on each antenna. I'm not an engineer, so I have limited knowledge on these subjects. What I am doing wrong? Everything maybe? I know this whole thing may sound a bit crazy, but when you live in a country were 1 dollar is 4 times 1 real, and everything you bring officially in pays 100% in taxes, it makes sense to try to get the most of the minimum, you understand. I am attaching some pictures and any suggestion or ideas will be most welcome. Thanks Tony Muricy - Rio de Janeiro, Brazil. I forgot to say that I goy a 15m long sma cable to connect my LPDA antenna to my rf amplifier on my cart. This way I can move the antenna to the best spot. Thanks
  2. Hey guys, I was told by one of the usual suspects that Remote Audio's MEon Life was recalled and that even after recall and repair, have been quite unreliable. I find that kind of hard to believe, mostly due to the great reviews on here. Maybe they have something to gain, or better margin on PSC stuff. Any thoughts?
