11 for sale on Reverb2 finishes at Thomann
- Size19"
This active antenna splitter sends one antenna signal to up to five Shure wireless receivers. It suits you if you run several wireless systems at once and want them set up together in a 19-inch rack. Holes in the housing let you move the antennas to another spot if you need to.
Pros
- Splits one antenna signal across up to five wireless receivers
- Eight BNC outputs give room to run several receivers at once
- Two BNC cascade connections let you chain in a fifth receiver or another splitter
Cons

If you run a Shure wireless setup with two diversity receivers, this antenna switch set is a good fit. It is passive, so it needs no power, and it comes with the HF cables and a BNC mounting socket you need to hook it up. Check that your receiver is on the compatibility list before you buy.
Pros
- Passive design, so it needs no power supply to run
- Works with two SLX4 or BLXR diversity receivers at once

- Size9.5"
If you run several Shure PSM transmitters at once, this combiner lets you share one antenna instead of needing one for each. It has 4 BNC inputs on the back, a BNC output on the front, and rack mounts, so it fits a standard rack setup. You will need to buy an antenna separately, since it is not included.
Pros
- Combines up to 4 Shure PSM transmitters into one antenna output
- Frequency range of 470 to 865 MHz covers a wide band
- Includes power supply, 4x BNC cables and rack mounts
Cons
- Antenna is not included and must be bought separately
- Supports PSM transmitters of up to 30 mW only

Shure PA421B Wireless System Antenna Combiner (470 - 865 MHz)
PA421B-E · Shure
3 for sale on Reverb1 finish at Thomann
- Size19"
If you run several in-ear monitor systems on stage, this one is worth a look. It combines up to four Shure P9T or P10T transmitters onto one antenna setup, so you do not need a separate antenna for each one. The metal 1 U rack housing and included cables make it a neat fit for a rack-based setup.
Pros
- Combines up to four Shure P9T or P10T InEar transmitters into one antenna setup
- Four BNC inputs and outputs on the back keep connections tidy
- Expansion port lets you cascade two combiners together

- Size19"
- Weight1.63 kg
If you run many wireless mics at once, this unit is built for that job. It works with up to 16 GLXD4R+ rack receivers and manages their frequencies across two bands. It fits a standard 19-inch rack, so it suits a busy stage or install setup more than a single-mic player.
Pros
- Dual band operation on 2.4 GHz and 5.8 GHz covers two frequency bands
- Manages up to 16 GLXD4R+ rack receivers in one system
- Handles the complete frequency management system for up to 16 GLXDR+ radio systems in parallel
Cons
- At 1.63 kg, it is heavier to move than a small unit if you carry it often

How to choose the best splitters and combiners
Signal Integrity
Shure's designs prioritize minimal signal loss and distortion. We're talking about preserving the articulation of a snare drum hit or the subtle breathiness in a vocalist's performance - that's what separates a professional sound from a 'something's not quite right' vibe.
RF Performance
Shure has a long history in RF technology. Their combiners are designed to minimize interference and maximize channel availability, which is absolutely crucial when you're sharing frequencies with other bands or venues with dense wireless setups. Less dropouts, more confidence.
Build Quality
These aren't flimsy plastic boxes. Shure's splitters and combiners are built to withstand the rigors of touring. Robust construction means they'll survive being crammed into a gear case and tossed around.
Isolation
Good isolation prevents bleed between channels. Imagine a backing vocal leaking into the lead vocal mic - it's a mix nightmare. Shure's combiners do a decent job of keeping things clean, though budget alternatives often fall short.
Compatibility
Shure's gear generally plays well with other brands, but optimal performance is, of course, achieved when using them within a Shure wireless ecosystem. It's like using Fender amps with Fender guitars - it just works better.
Buying guide
Okay, so you're wrestling with multiple wireless mics - lead vox, backing harmonies, that wandering tambourine player - and you need to get them all running cleanly into your mixer. Shure's splitters and combiners aren't just about functionality; they're about preserving signal integrity when you're dealing with the nuances of live performance. Let's be honest, a muddy wireless signal can kill a gig faster than a blown amp, and Shure's got some solid options to keep things tight.
Look, you can find cheaper splitters and combiners out there, but you're often sacrificing signal quality and build. The Shure units aren't the absolute cheapest, but they represent a sweet spot between price and performance. If you're running multiple wireless mics for a serious gig or tracking work, investing in a Shure combiner or splitter is money well spent - it's about preventing problems before they arise and ensuring your sound is professional.

Questions
Can I use a generic splitter with my Shure wireless system?
Technically, yes, but you risk signal degradation and increased RF interference. It's like using a cheap guitar cable - it works, but it sucks the life out of your tone. Shure's units are designed to work optimally within their ecosystem.
What's the difference between a combiner and a splitter?
A splitter divides a single signal into multiple outputs, while a combiner merges multiple signals into a single output. You'd use a splitter to send a vocal mic to both the stage monitor mix and the FOH mixer, and a combiner to consolidate multiple mics into a single wireless receiver channel.
Do Shure splitters and combiners introduce any latency?
Minimal. We're talking fractions of a millisecond, practically imperceptible. It's not a factor for most applications, but it's something to consider for very latency-sensitive scenarios like live looping.
Are Shure combiners bidirectional?
Most are. This means they can handle signals flowing in either direction, which is important for flexible routing and feedback management. Double-check the specific model specs to confirm.
How do I minimize RF interference when using multiple wireless mics?
Proper antenna placement is key. Keep antennas away from metal objects and each other. Shure's frequency finder tools can also help you identify clear operating frequencies. It's a constant battle, but a clean RF environment is vital.
