mr.incandenza Posted January 31, 2015 Report Share Posted January 31, 2015 Any chance to make them work with "only" 2 antennas using a MICPLEXER2 and a RF MULTI SMA? Quote Link to comment Share on other sites More sharing options...

Ze Frias Posted January 31, 2015 Report Share Posted January 31, 2015 I'm sure I read somewhere here that using the RF Multi SMA with the QRX200 is not recommended, as it overloads the front end of the QRX200, thus greatly reducing range. The reason the MicPlexer 2 is recommended is because it has a tunable 35MHz filter. Having said that, I don't know of any way you can setup all those receivers tuned into different blocks, on only one pair of antennae, without making some sacrifices. For example, if you have a pair of log periodic antennae, which are broadband and will cover the entire spectrum of your wireless, and use a two way passive splitter for each antenna to split the signal, one to the MicPlexer 2, and one to the QRX100 block 25, the MicPlexer will feed the rest of the QRX200s. The 2 way split will cause a theoretical 3dB insertion loss, so that would be the sacrifice in this particular setup. The loss may be insignificant in the grand scheme of things, but you will notice that your range on the QRX200s may be greater than that of your QRX100, due to additional gain that the MicPlexer gives. There are other ways to tackle this, but not without some sacrifices. Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted January 31, 2015 Report Share Posted January 31, 2015 Jose sums it up well. I have had good success using a passive splitter to link a single pair of antennas to two mic plexers to my system across blocks 24 and 20.

Jason Todd Posted January 31, 2015 Report Share Posted January 31, 2015 I've thought about doing the same as Kelsey. Good to know that it works well. Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted February 1, 2015 Report Share Posted February 1, 2015 Kelsey's solution should work fine, as the MicPlexers add back gain and more than compensate for the passive splitter's insertion loss. Quote Link to comment Share on other sites More sharing options...
mr.incandenza Posted February 1, 2015 Author Report Share Posted February 1, 2015 Thanx guys, I'll try and I let you know. Quote Link to comment Share on other sites More sharing options...
mr.incandenza Posted February 1, 2015 Author Report Share Posted February 1, 2015 any suggestion from the market for a passive splitter? Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted February 3, 2015 Report Share Posted February 3, 2015 I combined a pair of Lectro passive splitters into a single chasis to make it more bag friendly. Quote Link to comment Share on other sites More sharing options...
Aural Fixation Posted July 3, 2015 Report Share Posted July 3, 2015 Wandering Ear, do you have a thread illustrating your mod of the Lectro splitters? I'd love to know how you did that. Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted July 3, 2015 Report Share Posted July 3, 2015 Wandering Ear, do you have a thread illustrating your mod of the Lectro splitters? I'd love to know how you did that. I didn't really mod them so much as just combine them. The faceplate with the bnc's on them has all you need, so I used the chassis from one splitter and put both splitters on opposite sides.

David Marien Posted July 4, 2015 Report Share Posted July 4, 2015 I use RF multi with QRX200 (lower blocks TX), QRX100 block 25 and Lectro SRB block 26. It works like a charm both with dipole antennas and Zaxcom Bluefins. Whilst I don't have the technical knowledge to contradict the above arguments, this rig has undeniably been satisfactory to me.
