Combiners & Splitters

TX-8U Active Transmitter Antenna Combiner

The Radio Active Designs TX-8U transmitter combiner may be used on the transmit side of the UV-1G wireless intercom or on any UHF in ear monitor system. The TX-8U is superior to other transmit combiners on the market due to its high intermodulation suppression and full control of the RF power output of each transmitter.

Features Include:
Individual RF power switches at each of the inputs.
RF Power regulation so the output from the IEM or RF PL maintains a constant, predetermined output from that device.
Low Intermodulation distortion for a cleaner RF signal

TX-8/900M Active Transmitter Antenna Combiner

The TX-8/900M can be used with any UHF in-ear monitoring (IEM) or IFB systems operating in the 900MHz band, specifically 944-952 MHz – the entire spectrum now available through the FCC.

The unit allows the connection of up to eight UHF transmitters to one antenna. Advanced active-linear design reduces intermodulation products to exceptionally low levels to minimize interference while providing compatibility with all forms of modulation, including FM, AM, SSB, ENB, as well as a variety of digital forms, including FSK, and MIMO.

Features Include:
Connect up to eight UHF transmitters to one antenna
Advanced active-linear design reduces intermodulation products to exceptionally low levels to minimize interference while providing compatibility with all forms of modulation, including FM, AM, SSB, ENB, as well as a variety of digital forms, including FSK, and MIMO.
Individual channel indicators on the front panel show RF activity and amplifier faults
Antenna fault indicator warns of excessive antenna VSWR
Output power is selectable to 50, 100 or 250 mW, independent of input power level

V-8 VHF Antenna Splitter

The Radio Active Designs V-8 is a VHF antenna splitter designed to work with the UV-1G receivers. The V-8 receives signals from the VHF antenna input and splits the RF signal to eight outputs.

Two Versions:
1-IN/8-OUT VHF Receive Splitter, BNC
4-IN/8-OUT VHF Receive Splitter, BNC

Features Include:
A DC voltage switch to send VDC up the coaxial cable input to power a remote VHF filtered amplifier for long cable runs
RF Gain control to customize your setup with proper RF Gain Staging
