Just curious if any of you have found solutions for combining lots of RF (20+). I am currently using the Sennheiser combiner but would like to consolidate the space if possible. Thanks!

Transmitter combiners are limited to 8 inputs per 1RU, whether it be the PWS GX8, RAD TX8, Shure PA821A, or Sennheiser AC3200.

an 8 channel combiner in 1u is already pushing it, so more channels would just mean a bigger combiner. 20ch would be 4-5u minimum. Also remember that as you combine more channels you need to amplify each channel more in the combiner, giving bigger heat issues.

Are you talking about combining IEM transmitters, or wireless mics. IEM combiners are generally limited to 8, but there are bigger microphone receiver antenna distribution systems.

The Shure PA821 has an accessory 2 to 1 passive combiner on its front panel, and the manual shows it being used to combine the outputs of two PA821's for transmission via one antenna. (so 16 to 1). I haven't done this myself on a show site, but we've rented out systems using that feature with no complaints from the customers.

There are plenty of solutions for these kind of large combiner projects, but they tend not to be listed on consumer websites, since they are special order items.

People like Saras make these things for big TV projects and the like where you might have to combine 10 or more pairs of antennas to feed a single rack of RF receivers.

What is your application?

[Jim McKeveny]

We are all running blind here: are you transmitting or receiving?

We also have to assume that all of your intermod, frequency band(s), and antenna homework has been done.

If you are searching for cheap vs. best practice, look at Mini-Circuits splitters/combiners. If you REALLY know what you are doing some of their products may be of help. If you REALLY DON'T know what you are doing enlist professional RF help.
