Introduction:
A ground loop in your AV system caused by antenna connection or TV cable is very common if you have your computer connected to the same system. This type of ground loop problem can be solved by using suitable isolator between your AV system and the antenna cable.
Antenna isolator is very convient way to solve antenna connection related ground loop problems.

Impedance: 75 ohm
Length: 134 mm
Connector A: IEC-liitin uros
Connector B: IEC-liitin naaras
Frequency range: 2-870 MHz
Isolation: Max. 500V CA
Comments on the product:
This antenna isolator has proven to be a well working and reasonably priced product. I have used it many times to solve ground loop problems on audio/video systems. It has worked well for both TV (antenna signal, cable TV) and FM radio signals.
The product is simple to use. Just install it between the antenna cable and the equipment. This product has male IEC antenna connector on one end and IEC female antenna connector on other end. It plugs nicely between the antenna cable and the equipment in the antenna wiring system used in Europe.
The products work well. It causes some small antenna signal attenuation, but not too much. It seems to be quite well shielded agains interference from outside sources (better shielding than some other isolator circuits I have tried, but not as good shielding as direct antenna cable has).
I can recommend this product for solving audio/video system ground loop problems that are caused by TV/radio antenna connection.
Note for users outside Europe:
Jebsee makes also a version of this product that has F connectors in it. JEBSEE 634ML CABLE/VCR GROUND BREAKER FEED THRU SURGE
PROTECTOR is a version that has the isolator, around one meter of antenna cable and two make F connectors. I have also used this and it seems to work also well.
