I'm just doing some cleanup....$$ old Spaun switches, etc. Boy, those were the days.

Do you guys see in what application just short of a MOCA network - any use for diplexers ? I used to use them when I carried OTA / DTV over a single coaxial. Have not used OTA forever...Pretty much straight DTV feed. SWM switch - single run to each receiver.

Just debating what I'm going to do with these $$$ Channel Vision diplexers & or if I will ever need them again.

If you won't use them, put them up on eBay. Otherwise, hold on to them, because you never know if they'll come in handy. They're small enough...

Likewise here - ton of diplexers, signal lockers, multi-switches, a 5LNB. All obsoleted when I went SWMLine. Need a buy\sell forum up here.

Never mind, there is one, never noticed that before.

you can use a power passing splitter in a swm application instead of a power inserter. We have been going through hell lately to get the appropriate equipment to get our jobs done. swm power inserters have been hard to find.

All SWMs [LNB or module] need a PI.
No one should try to power them off a receiver. :nono:

I think (hope?) he means that you can use a splitter that passes power on one leg to enable the PI to source the SWM.

I'm afraid that would be a stretch, because of the mention of PIs being hard to come by.

I'd think you could use any old 21-24 volt, 2+ amp power source. I've bought lots of 2 to 3.5 amp, 15 to 18 volt laptop switching power supplies on eBay for under $20 each for all kinds of purposes.
