Q: 1. Is this compatible with the UA844SWB antenna distribution system?

A: Yes, the PA805SWB antenna is compatible for use with the UA844SWB antenna distribution system.

Q: 2. 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.
