I understand that the voltage comes from the rcvr. Bit are you saying there is no way the voltage can return to the hub from the lnbf and try to pass thru a power passing port?

I know you guys think I've ruined my credibility here, but do me a favor, go test a jumper on port 2 on any lnbf that has more than one port, while a rcvr is connected to port 1 and you will see voltage
Not a lot, but you will see voltage. While testing on the client port of a node or hub, you will not detect voltage.
That's how you get water migration when you leave jumpers attaches to a dish. The voltage pulls the water in
From my experience with electrical equipment, it doesn't matter if voltage is present or not. It can't just make a u-turn and damage the source, that's just not how voltage works. Not having a cable connected to a port creates an open. You terminate the port for the safety of equipment and personnel. A terminator is just the professional way to close off an active source, it doesn't create a loop back
In the interest of complete credibility I just did what you suggested. I try to never post something I'm not positive about so I just hooked up a 211K to a K2 EA dish with a new Hybrid LNB. The 211K is now playing and there is absolutely no, none, zero voltage on the other wire coming in from port #2. And that's a fact.
I'll bet if you had a piece of cable with a barrel and terminator on 1 end and an ohm on the other. You wouldn't have continuity with 1 lead on the jacket and the other on the stinger.
I've tried that before chasing my tail before I realized that won't work.
If I'm wrong I'll accept it, but all the evidence Leeds to the fact that you shouldn't terminate a power passing port.
