What’s the best solution for combining 10 or more channels of wireless to antenna?

Sennheiser and Shure each have 8ch units, professional wireless’s largest combiner also /
seems to max out at 8ch.
 
Dude!

I love RF Venue stuff. Does the cascade set up work for combiners as well as distributors? My problem is that every combiner I can either supports 8 or 4 Txs, I need at least 10 out.

Check out https://www.minicircuits.com/ I'm using their products in both splitting and combining roles for Sennheiser receivers and IEM transmitters respectively. They work very well--just make sure that you specify the impedance and connectors that you need.

To combine 10 you need 3 RF Venue Distro (best bang of buck splitters). PM me if you need pricing.

So... if we're talking about "transmitter combiners" and you need 10 INPUTS, you can consider:

1) using a passive combiner to combine two active combiners (8+4 for example).

Shure PA821 (8 input combiner) + PA421 (4 input combiner) combo will give you the 12 inputs you need and both have a passive combiner built-in the front of the unit. You will lose 3 dB (half-power) on each carrier, but hopefully you can compensate for that upfront with transmit power from the IEM units. What model of IEMs are you using?

2) Second option: use 2 transmit antennas. No passive power loss.

Hope this helps.

Cheers
