Problem with APC coax cable protection

This question was originally posted by Xarx on APC forums on 1/15/2013


I've bought the surge protection APC P5BV-FR with coax cable protection, in order to use it with cable TV. The coax protection works fine, but it filters out all TV channels on the 3rd digital multiplex (674Mhz, channels 22-31; I'm not sure about the terminology). Hence, this coax cable protection is unusable to me.
I haven't found any documentation to this surge protection describing which frequencies are inhibited by the coax cable protection.

My question is:
Should I claim for the surge protection replacement, or is this its "feature"?
Would be this frequency inhibition different for the German version of this product, P5BV-GR?
Or, can be this frequency inhibition "shifted" to another frequencies?

== Details ==
Without the surge protection:
* DTV-C signal strength: 65%
* Signal quality: 99%
With the surge protection
* Signal strength: 60%
* Signal quality: 99% with the exception of the 3rd multiplex
* Signal quality: <10% for the 3rd multiplex.
(I don't know the meaning of these numbers, this is what my TV displays.)

Martin.

Unfortunately, when you use a product like this, you are essentially adding a "middle man" which creates signal loss. I also don't fully understand this type of terminology either as far as why this would happen. It's possible it could be a product issue but I would guess it's not. Personally I would suggest calling tech support for your area and see if they can replace it. The problem with that is, we cannot be sure it's our product that's the problem but they may be willing to send you another to test.
