Here are the answers to some common questions we receive:
Will Kathrein RET controllers work with other vendor antennas and RET devices?
Kathrein is one of the original members of AISG which created a general standard for communication to antennas via RET ports. Kathrein has 3 controllers in the market right now.
All 3 controllers have been extensively tested with Kathrein and competitor antennas by both us and our customers. 99% of the time Kathrein controllers can do anything needed on competitor antennas if competitors have followed the AISG standard.
Below are some links for examples of Kathrein controllers working with 3rd party antennas.
How do I scan/control/load 3rd Party antenna using ALC ?
Kathrein ALC controller can be used to control and configure 3rd party antenna line equipment.
How do I scan/control/load 3rd Party antenna using PCA?
PCA has been tested with many other vendor antennas. To do this follow options shown in quick guide below. Note that Kathrein does not guarantee full interoperability with non-Kathrein products. If a product cannot be scanned, we recommend you contact that company support.
How do I scan/control/load 3rd Party antenna using CCU?
CCU has been tested with many other vendor antennas. To do this follow options shown in quick guide below. Note that Kathrein does not guarantee full interoperability with non-Kathrein products. If a product cannot be scanned, we recommend you contact that company support.
Can I daisy chain Kathrein antennas with other vendor antennas?
Yes, but it is best to only configure one type at a time and wait 1 minute before sending next tilt command. This will give antenna enough time to complete the action.
After I added Kathrein to daisy chain with other vendor antennas, why is it not scanning/adjusting properly?
In some cases, other vendor controllers, base station equipment or Remote Radio Heads have a limited power output. Kathrein devices are designed to have a low startup current and operating current; but many 3rd party devices consume much more power. In some cases, this can cause unstable operation when multiple vendor equipment is daisy chained together.
It is recommended to wait 60 seconds between one tilt command and the next one, this will reduce overall current consumption on the AISG line.
It is also possible that there is a combination of AISG 1.1 devices and AISG 2.0 devices. This may require to scan for AISG 1.1 then second time for AISG 2.0 devices.
How to control Ericsson Air Antenna with Kathrein ALC?
The Ericsson Air Antenna can be controlled with Kathrein ALC. It will require the use of the coaxial cable that comes with ALC, it has a small RF connector on side that connects to the ALC and the other end has a 7/16 DIN connector to interface with Ericsson Air Antenna. Control of the AIR Antenna is very similar to other antennas; more details are shown in document link below.
