[Moon-net] Q. Measure for OM6AA round septum

[Koellner, Guenter]

Hello,

I described my design of the round Super-VE4MA with Septum Polarizer in latest DUBUS, where it is also shown how to find the dimensions for the septum plate.

But I did not answer because Sven was asking for the 5-Step-Septum, and I am using the known one with 4 steps.

73, Günter

For the round waveguide do you need different size of steps. Diameter of
round feed is higher.

Hi
Does anyone have the measure (in mm) for the round septum (OM6AA) described
in latest (1/2007) DUBUS?
Can I use the same the 4-step septum from OK1DFC? Why are 5 steps better
than 4 steps?
I will use the measure only to fabricate one psc just helping a friend to be
1296-EME-QRV.

73 Super tnx de Sven SM5LE
