We still need to know which Stations are affected by Interference generated by HTPC. If you are TRYING to receive Ch2 or Ch6, be advised that GE-29884 is primarily a UHF Antenna, with a simple 0 dBd Gain Dipole for Ch9 and NEGATIVE Gain with excessive SWR for Ch2/6. I can provide advice re simple DIY Indoor (or Attic) Antennas for Ch2 and/or Ch6 if you let me know which you are interested in TRYING to receive.
Most Surge Protectors have minimal IF ANY suppression of RFI/EMI....and only a FEW are capable of providing RF Isolation between the various attached Devices in order to suppress EMI/RFI generated by HTPC from being conducted to OTHER devices via the AC Power Cord. I would recommend that you purchase one of the Tripplite ISOBAR Surge Suppressor Power Strips [and ISOBLOC Wall Outlets], which provide ample RF Isolation BETWEEN the attached Devices, such as the following:
If you are looking for a less expensive alternative, many BELKIN Surge Protectors also offer RFI/EMI Filtering, although not as much as ISOBARs provide, for example:
I DO NOT advise running TV/Cable Coax thru the Coax Filter/Surge Protective Device included in SOME Power Surge Strips....the LAST thing you want to do is to have VERY high voltage (and EMI/RFI signals) come anywhere NEAR your sensitive and pricey Electronics. IF you think you WANT this sort of protection, there are devices that screw into the Ground Block...which MUST be Grounded to drain off Static Electricity that forms when high winds blow across the Ungrounded Elements in a TV Antenna:
Sorry about the missing links in this 2012 post...here are a couple that I could recover:
In ADDITION to suppressing Interference Conducted via the HTPC's Power Cord, you will likely ALSO need to suppress Interference Conducted (and Emanated) via OTHER HTPC Cable Connections....including one around Power Cable JUST AFTER it exits the HTPC to suppress Emanated Emissions (i.e. via the Air FROM HTPC's Power Cable). A bag full of the fol. Clamp-On Ferrite EMI Suppressors can be used on ALL of these other Cables:
[Note Bag of Assorted Sizes is available]
FYI: An LTE Filter MAY or may NOT help your situation, so you might want to consider it after all other alternatives have been thoroughly explored. Also be advised that I have not YET seen any LTE Filters designed for the NEW UHF Band (470-608 MHz) which is currently being implemented [San Diego RESCAN DAY was 14 Mar, rest of SOCAL is mid April]....so you will NOT be protected from possible LTE 600 MHz Band Interference [existing or soon to be activated] using currently available LTE Filters, such as from C-M, et. al.
