Advice Needed Gd satcom/prodelin depolariser

[g host]

Hi.
Browsing from some time about depolariser i have noticed three models from GD Satcom/Prodelin, i wonder, what is the diffference. Why is need for three models ?

First is the usual short depolariser for the prime focus antennas (now discontinued).

Second and third are the feed systems for the offset 0.6 f/d designs (1251/1381/1384) . Gold might mean it is Intelsat Approved for transmit (F1 ) to the 1.09 standard though this wasn't the case when they were selling them in the late 90s.

There should be a model number on the outer carton that determines the production., along with testing and quality control, the last two won't have much use for a receive only system since the end furthest from the feed is a transmit port with the upper frequency flange.

Are they yours ?

No, pictures from the net.
I know about TRF part. My plan is to buy first or third and attach at the end c-band omt.

I wonder, what version they have for 0.8f/d ? I mean for 1244 model.

None at all.

Please carry out some research before posting again.
