Waveguide septum filter. From: Steve Utick Sent: Thursday, March 24, 2016 5:27 PM To: af@afmug.com Subject: Re: [AFMUG] Ceragon IP20C
It's pretty impossible to show in the interface, as the physical radio itself is exactly the same. What makes it TX high or TX low is the position of the diplexer in the radio. You can flip them to make the High radio a Low and vice versa. I've attached a picture of the diplexer out of a Ceragon 6GHz radio. You can see the L and H markings on it. Simply flipping the diplexer end for end changes the radio from TX high to TX low.

Unfortunately, the geniuses at Ceragon don’t seem to have figured out how to show that in the interface anywhere. So I guess I’ll have to climb one of the towers to figure out which it is. So for example, if I’m using channel 11200 and 10800 then the H radio needs to be assigned the 11200 channel? And the 10800 the L radio? Do I have that right?

The radios will happily let you program frequencies into them that are outside of the diplexers that are in the radio, they just won't work very well, if at all.

IIRC, the label that lists the PN shows the frequency range, but that may have been one of their other models. Been a little bit since I laid hands on one. -- IgniteNet ca...@ignitenet.com www.ignitenet.com We're hiring! Ping me.
