The PA805Z2-RSMA Passive Directional Antenna is considered a key part of any GLX-D Advanced Digital Wireless installation. These antennas both improve reception of GLX-D transmitter signals and minimize interference from any 2.4GHz sources near receivers with appropriate installed placement.

Main Features

  • Improved wireless reception: 8dB of passive directional antenna gain
  • Improved rejection of interference from 2.4GHz sources: 24dB front-to-back ratio for improved rejection of off-axis signals
  • Can be painted with non-metallic paint to match mounting surface
  • includes 3,05m RSMA cable.

Are there different transmitters?

No. There is only one series of transmitters. These can be used with GLX-D receivers (GLXD4 and GLXD6) as well as with GLX-D Advanced receivers (GLXD4R).

Can I use standard GLX-D Systems with the new GLX-D Advanced systems?

If you are not using the Frequency Manager, then the GLXD4R receiver operates similar to a GLXD4 receiver. In that case, follow the guidelines and best-practices for GLX-D.

If you are using the Frequency Manager, we recommend only one GLX-D standard system.

How many channels I can run with GLX-D Advanced?

In an environment with no other WiFi devices you can run up to 11 channels. Under typical conditions (one WiFi channel is active) you can run up to 9 channels. The more WiFi channels active in an environment, the lower the max. amount of channels. Please be sure to use frequency manager.

I have two channels of GLX-D Advanced. Is the Frequency Manager necessary?

No. When running two channels we recommend using the UA221-RSMA antenna splitter to split the incoming antenna signal to the two receivers

What are the main differences between GLX-D and GLX-D Advanced?

The GLX-D Advanced receiver is rack-mountable and features detachable antennas. This allows users to use directional antennas, helping to increase system stability in environments with other WiFi sources.

The GLX-D Advanced Frequency Manager creates a shared group of frequencies for all receivers to use and automatically assigns frequencies to each receiver. If interference occurs, the frequency manager assigns new frequencies without audible dropouts.

What is the difference between Group A and B?

Group A is optimized for low latency (4 ms), ideal for a channel count of 6 systems, maximum 9.

Group B has a higher stability and a higher latency (7,3 ms), ideal if you experience interference or need to run 9 to 11 systems.
