Dear Sat Guys,
recently I got an Andrew 2.4m dish wich was originally used for C-band. I would like to use it for C-band as well. What would be the easiest solution to make it usable for both polarisations? R+L
to the forum DL10M
That is a nice looking scalar and feed. I have not seen that before. I would be nice to find one for both polarities. But I'm sure it would be expensive.
But easy would be to buy a voltage switched c-band LNBF with a conical scalar ring. Titanium Satellite - Store
I would try and adapt that LNBF to the stock conical scalar you have first. And if there wasn't a good way to make it fit I would use the other.
If you want to spend a lot of money, you can buy a CPR229G flange tee plus a second LNBF for the other polarisation. But the LNBF alone would be around 250$. I guess there is no CPR229G dual polarity LNBF.
Another thing is the dielectric plate. It is known that these plates cause losses (-3dB ?). That's why some people use the AV-COMM waveguide polarizator from Australia. Any experience with that?
Anyway we still have very low temperatures in Germany. I am not in the mood to touch cold metal in winter. So my first tests will not start before easter time.
