They should be the same, and just labeled to be labeled, and not mix them up.
I can't imagine why a DVD player would need a surge supressor.

Coaxial connector on power protectors
I am setting up a HT and have a question about the power component. I am looking at the Monster Cable and Pure AV (Belkin) surge protectors. I like the surge protection, the power conditioning and the consolidation of power outlets. I looking at the models that have multiple coaxial connectors. I have two drops from my SAT to my dual tuner DVR. These strips only label one of the coaxial connectors as SAT, the other is typically CABLE. High end ones have a third one, AUX.
Are these coaxial connector the same and just labelled for typical usage or do they have different electrical characteristics and therefore putting my second SAT cable through the CABLE connections will mess with the signal?
One model of the Pure AV has SAT and DVD. What does DVD got to do with coaxial connections?

Just to drop another name in the hat, you may want to check out products by PANAMAX , if you haven't already.
The PANAMAX 4310 has the dual SAT feature you want, and for probably about the same price as the BELKIN components, and more than likely FAR LESS than MONSTER.
Worth checking out, IMO.

The PANAMAX 4310 has what I want but is seems more expensive at $249 MSRP.
Also, with no disrespect for Larry, I appreciate the feedback, I remain sceptical that all the coaxial connections are tuned to the same frequency ranges.
For example, the PANAMAX explicitly states that 2 connectors are for SAT and one is for CABLE. I believe the frequency bands for SAT and CABLE are significantly different and if there is any signal "cleaning" circuitry behind the connectors, it will be tuned for the frequency bands of the specific application. Therefore, a CABLE connector may "clean up" the SAT signal, thereby degrading it.
Can anyone confirm this one way or the other?

Heh, I just found the info based on the PANAMAX product.
For CATV:
For CATV:
Yes, CATV and SAT are different frequences and should be routed properly.
It is the same reason a cable TV splitter (5 to 1000MHz) will not pass a SAT signal properly.

Street prices for PANAMAX is closer to $125 to $150 putting in the same range as the high end Belkin and Monster products.
The street price of $125 to $150 is for the PANAMAX 4300
The street price for the PANAMAX 4310 (the one that interests me) is $160 to $200.
Which makes it more expensive, but not that much more expensive. Seeing that it clearly has what I want and the others are questionable, I guess I will order a 4310.
Thanks for the info!

Version,
There are no active electronics in the surge surpressor for coaxial cables. Either will work for CATV or SAT, try it. The ideas is to match the impedance on each end of the coax. It is desiged to minimize the effect on the intended signal that passes through.
It is true that SAT won't work through a CATV splitter. The idea is that you can't split the higher frequency SAT signals. Probably because the split signals would result in standing waves and thus an impedance mismatch.

Nah! You can't split a Sat cable to 2 receivers because it also carries low voltage signals from the receivers to the dish/multiswitch. 2 receivers can't send 2 different low voltage signals over the same line. A high frequency splitter can be used on a Sat system between a multiswitch and a dish though. There are 4 of them in a wiring digram at http://www.solidsignal.com/manuals/w...6-PhaseIII.pdf for example.

I believe that is true, but isn't there passive electronics (capacitors and / or inductors) to create bandpass filters tuned to the intended frequency range? If so, using SAT frequency bands in a CATV connection could shunt most the signal to ground?
What is the empirical findings of this discussion? Anyone have two SAT cables connected to a SAT and CATV and truely experience to differential between the quality of the reception from both tuners? If so, what product / model?

Does that mean the SAT connection on the surge protection between the dish and the receiver has to pass DC (assuming you mean low DC voltage) while the CATV does not?
Does that play a factor in the SAT versus CATV connectors, i.e. the ability to pass the requisite low voltage?

I don't know for sure, but I don't think the coax connections on surge surpressors or line conditioners have any filtering components (caps or inductors). I think they only have surge surpressing devices like MOVs. I think greywolf is correct about not splitting SAT because of power. Both Types of connections will pass power if they only have a surge surpression device.

I decided on the PANAMAX 4310 based on a tip here on the forum.
This device uses different clamping voltages for SAT versus CBL, so there is an electrical difference.

Whatever the reason, my sat cables (Dishnetwork) pass through a surge protector with no problem. Forgot the brand.
PS. It has sat & cable connectors. I suppose with different clamping voltages.
