There's a difference between Rx/Tx antenna and normal ones?

enb141 Even if you get one of those you will still need to find the way how to mount it on the lower feedarm. Could you show some pictures of your antenna and all the spares it has?
Only the first feedhorn from your previous post can fit to an offset dish, the second one is for PFA.
So, original CM feedhorn will cost you ~100 bucks, flange LNB may cost ~30 bucks, plus delivery that will cost you ~200 bucks.
To fix LNB to the feedarm you will need special metal frame, which looks like this View attachment 133889 If you do not have it in the set, then you need to get it somewhere or DIY.
And, again, IMHO it is much easier to mount simple universal LNB like IBU and get pretty much the same reception results.

The BUC transmits on one polarity and receives on the other, so reception is single polarity, and the plumbing is set up to filter out as much of the other polarity and band as possible in order to minimize de-sense from the TX signal. Kind of like a pass band/reject filter combo with waveguides and stubs. The TX signal is well above the RX signal spectrum-wise, so unless the plumbing (waveguide) is modified you won't be able to receive much through it.

I have a couple of those BUCs here, I admit I have never taken them apart to actually see the plumbing inside. There may be a way to separate the TX bandpass section from the feedhorn, and add an adapter for a second LNB? RimaNTSS might be able to add from his experience here.

The original BUC feedhorn would likely be the best to utilize if you can somehow. I might take one apart later here and see what can be done...
