Newbie question about Sennheiser Antenna combiner
« on: February 03, 2014, 07:28:05 PM »

I'm just getting started on this wireless world and I use 5 Sennheiser wireless in ear systems and 2 wireless mic systems. I saw the Sennheiser Antenna Combiner and I really liked it cause it can transmit power up to 4 systems through the BNC cables, saving a lot of outlets. But what else a Combiner does? Lets say I run monitors from stage left and want to increase in ear levels in stage right. Could I get this combiner connected to one of those UHF giant antennas to this job? I mean, it combines 4 signals into one antenna, but are the signals kept individual or are they really mixed into one signal?
What about the antenna splitter? Could the FOH enginner get these signals from the stage and split them into the mic receivers?
Sorry if it's a dumb question

Ears are transmitters. Mics are receivers. Two different rf directions. Combiners just allow less antennas. The frequencies are separate. The rf combiners have nothing to do with splitting mic signals between FOH and monitors. That is done in the audio side.

Read the articles on this page:

There are no dumb questions. After you digest the above info, please ask more.

Nice articles. You answered my question about the Combiner. Signals are transmitted separated. But then what the use for a splitter?

Combiners are used to put multiple transmitter signals to 1 antenna.

Splitters are use to distribute *received* RF to multiple receivers.

Tim nails it right on the head (as always!).

Combiners are used to put multiple transmitter signals to 1 antenna.

Splitters are use to distribute *received* RF to multiple receivers.

So, in your case, you will need one combiner (well, actually two, if the combiner has the same 4 unit capacity that my splitter has) for the IEM transmitter system, and one splitter (ASP) for the handheld wireless microphones. With my 4-unit rack, I have four units mounted two-side by side, and the third 1U space I have the ASP and the front-panel antenna mounting kit, so the two main antennae are conveniently located on the front of the rack.
