The sennheiser antenna combiner in earsfrom sennheiser antenna combiner in earsis a passive device (no power supply needed) that takes four incoming RF signals and combines them into one outgoing antenna source. The combiner is used in applications where up to four different antenna sources are required, and only one antenna output is available or desired.

Combines four incoming RF signals and combines them into a single outgoing antenna source

Passive (no power supply needed)

Works with 72, 216 or 863 MHz

Lightweight and mountable

Related Questions and Answers

Q: 1. Does the bundle include the 12v power adapter cables?

A: Yes. The 4 power cables are attached to the combiner unit and plug directly to and power up the individual channel units.

Q: 2. Can I use IFBT4's with this unit? They transmit at 250mW. Wondering if this can attenuate or handle that kind of power.

A: The Lectrosonics M2C accepts a maximum input of 100 mW per port, so no, they would not be recommended for use together.

Q: 3. If I'll use two A1031U antennas, with two 5m BNC cables, direct to the G1 EW 100 receiver, what is the optimal distance between them if I work on 550.000Mhz ?

A: For the best coverage you will want to place the antennae as far from one another as possible.

Q: 4. Can you combine IEM and IFB RF signals of different output strengths? For instance I have a Lectrosonics M2T that has two output carriers of 50mw each. and a Lectrosonics T4 IFB transmitter that outputs 250mw. Can I combine them all with this to a single antenna?

A: It is possible to use transmitters with different power output levels with the RF Venue COMBINE4 - 4-Channel Antenna Combiner. This combiner is a unity device that does not affect or change the output strength of the transmitters connected. It does, however, have a maximum input level of 100mW and would not be compatible for use with a transmitter pushing 250mW such as the Lectrosonics IFBT4.

Q: 5. Does this come with Rack Ears?

A: No, the Sennheiser AC 41-US Active Antenna Combiner does not include rack ears with purchase. The Sennheiser GA 3 Rackmount Kit (BH #SEGA3) can be purchased for rack mounting this combiner.

Q: 6. can use this for transmitting device (In ear monitor)?

A: Yes, the Sennheiser A 1031-U Omnidirectional UHF Antenna can be used with Sennheiser G4 IEM transmitters.

Q: 7. Which antenna specifically comes with this kit?

A: A2003 UHF Wide-Band Antenna Sennheiser ADP UHF Passive Directional Antenna for EW-D Wireless Systems (470 to 1075 MHz) B&H # SEADPUHF4701 MFR # ADP UHF (470 - 1075 MHZ)

Q: 8. Can I use them for iem receivers? How long can I extend the antenna with a bnc cable? Thanks

A: Yes, the Sennheiser A 1031-U Omnidirectional UHF Antenna for Evolution Series could technically be used for IEM applications, although it is not ideal. The Sennheiser ADP UHF Passive Directional Antenna for EW-D Wireless Systems (BH #SEADPUHF4701) is more ideal for this application. BNC cable can be used in lengths up to 100 feet or more, but will experience some level of loss over long runs depending on the type of cable used.

Q: 9. what purpose is the power input and power output?

A: The PA411 not only distributes the RF from the antenna but also power to additional PSM transmitters. It will cut down on the amount of power suppiles needed in the rack.

Q: 10. Do i need 2 of these for true diversity?

A: Yes
