I need to buy a few terminator caps for a splitter of mine and a friends. Will this one work? Or will a few from a local RadioShack work? Personally, I would rather support a company like Solid Signal.

The picture of it doesn't seem like the ones DirecTV supplies so I decided to ask here; will this one work without any harm to my system?

Thanks,
Kevin

Yes those will work however when I needed to order some I found it was cheaper to order a 1x8 with free shipping for them than it was to order them individually.

Terminations are about the only thing that "it really doesn't matter".
They're made up of a 75Ω metal film resistor, mounted in a F-Type connector.
There is no "3 GHz rating", as they "pure resistance".

Find them anywhere close & cheap.

When I needed them I got them from eBay. There are some promising ones there now, like a 10 pack for $5 with free shipping from a seller with very high feedback.

Thanks for the info guys. I appreciate it.

I just bought a 2 pack from Home depot. $3.00 for 2.

This is true for most residential systems, but if there is voltage on the port that you are terminating it is required that you use a capacitatively-coupled terminator that won't conduct the voltage to ground like a standard 75-ohm terminator will.
Examples of this type of situation include the thru-ports on a SWM-32 or the thru-port taps in a cascaded system such as the MST-771, usually only found in larger residential or commercial systems.

I might add that these terminators are not commonly available, but may be included with those components that need them. The ones I'v seen have an elongated "nipple".

There is an example of these voltage-blocking terminators in use on an MFT-771 inside the cabinet and at the bottom of this linked page: http://www.pdisat.com/documents/MDU_COMPLETE_PDI-SAT.pdf

While I agree terminations/resistors shouldn't be using where DC is present, why would someone be terminating the through ports [or cascade out] of a SWiM-32, and is there any voltage there?

You may be right about those ports on the output of the SWM-32.

The SBCA MFH2 training says "all cascaded ports of the end units should be terminated with voltage-blocking terminators".
If the SWM-32 is conneded to the thru-ports of an MST-771 tap (with voltage present), would the voltage be blocked within the SWM-32?, or would you need to use an additional MST-771 and connect the SWM-32 to the tap ports of that MST-771?
I don't have access to one of these to test for the voltage, but I have used a regular terminator on a powered line...and it gets HOT!

"I would guess" [not having a SWiM-32] that the cascade outputs, would be like those on the SWiM-16, or those on the SWM8, which are legacy ports, so no different than those on the outputs of a WB68 [no voltage or need for terminations], "since they're outputs from a switch".

Does the IRD port of a PI29 need a terminator?

 

[veryoldschool]

Does the IRD port of a PI29 need a terminator?

Yes & no.
If the PI is connected to a port without RF [PWR], then it doesn't.
If it's connected to one that has RF [SWM/PWR], then it does.

 

[phoneman06]

Thanks. Mine is connected to the DC/PWR port and it has a terminator on the PI29 now, so I will remove it once get home.

Doesn't need it and doesn't hurt anything to leave it either, as there is a DC block.

I would think it could still benefit from some form of cap if for no other reason than to keep it clean

so if you still have the little plastic caps that came with it that could server to keep that port dust free
