Converting outdoor antenna from 722 dpp to hopper 3 dph (1 Viewer)

Hello all, first post here. I looked for topic discussion about this upgrade and could not find it.

I currently have a failing 722 unit with original western arc TurboHD dpp, so I decided to upgrade to hopper 3. I bought a dph lnbf (less antenna), hybrid solo hub, hopper 3 and one Joey 4k.

Can anyone tell me if it's possible to remove the old dpp lnbf and replace it with a hopper 3 style dph lnbf? I have seen posts about people swapping lnbf's on 1000.2's, but I have not been able to figure out whether my particular 722-era TurboHD antenna reflector and arm is compatible

Upon trying to swap the lnbf, I noticed that the old dpp lnbf has a plastic "key hole" which is missing from the dph lnbf. This intentional design change makes it impossible to mount the new lnbf. I am now thinking that 1000.2 reflector and arm assemblies differ over the years.

Do I need a whole new outdoor dish antenna assembly, or what?

I was hoping to avoid replacing the whole antenna assembly thinking I could avoid realignment.

Here's pics of old lnbf vs new and my original outdoor antenna. Thanks for any ideas!

If the DPH LNB doesn't fit your old dish it is definitely NOT a 1000.2 it's either a 1000 or a 1000.4 so yes you will need to change it.

I researched 1000.4 lnb' and that looks like you have a 1000.4 dish.
You would need to replace the dish with a 1000.2 dish. The mast are
the same between a 1000.2 and a 1000.4. some times you can find a
used dish for $0 to $40.00 on Craig's list.
