Parts Express Cable TV in-Line Coaxial Surge Protector

I ordered this as I have been having problems with blown HDMI ports on my Samsung UHD TV that just started late last year. I am using a good quality surge suppressor so suspected that there was possibly a spike coming through my Xfinity cable TV coax. Just to be sure I ordered this coax suppressor. This part is plug and go - no settings on the TV need to be changed. The quality of the TV's picture, sound and operation was not impacted by the use of this part. I have Xfinity X1 service which uses a technology called MOCA (Multimedia over Coax) which is essentially internet service running over the coax cable which can only be accessed by the Xfinity system. This internet over coax permits you to record a program on a DVR in 1 room and then watch in another, downloads the TV schedule from Xfinity's servers, etc. If a X1 connected TV can not use MOCA then the Xfinity service will not work. This part, as advertised, is MOCA compatible and all X1 functions continued to work after connecting this suppressor. I also tested this suppressor on the coax connected to my Xfinity internet box and there was no impact on home internet performance. I tested the internet speed before and after attaching this suppressor using Ookla’s speed test and the speed, jitter, packet loss, etc. were virtually identical with and without the suppressor attached. I can’t attest to how effective this part would be with a surge coming over the Xfinity coax but at least I am sure that the use of this part won’t make things worse and based on the specs will almost certainly reduce the possibility of an electrical surge damaging my equipment.

Showed up on time and works great

Needed this to set up an antenna. Signal was adequate and provided enough power to pull the news during hurricanes when running off a generator. Just screw in and plug in - easy to use and did a great job.

perfect for my use. inline surge for my OTA setup. still get free HD using this surge protector

The item is a lightning arrestor. If (when) it works it will be what it was made for. If it doesn’t work then the house will be in jeopardy from a lightning strike. The ratings say that it will work as intended.& I bought it with the intention that it does.

Good price. Hope it works

Easy installed inline and forget about any surges in picture quality.

Great!

Late arrival but the latest. Excellent

Excelente producto y mejor tiempo de entrega.

Good one

This inline filter seems to be made from quality material. Unfortunately, I had a signal problem with the one I recieved, but the company quickly addressed all of my concerns. So no worries.
