I just ran cable from my HDTV up to my attic and will eventually hook up an antenna. The run was right at 75' so I opted to use a 25' cable connected via a pass through male to male connector to a 50' cable rather than run 1 100' cable. My hope is that this will have less signal loss due to the shorter length (RG6 the whole way).


My question is - what is the loss through such a connector? Is it measurable? I'm assuming it to be in the 1 dB range but have no basis for this. Thanks.

Would have been better to use the proper length cable even if it mean cutting a 100' cable to length and putting on a new F connector. Any connection is going to degrade the signal a bit because there is never a perfect impedance match. But you probably won't see a difference. And you probably won't see a difference between what you did and 100' either.

The loss how un-measurable it really is, means nothing (bsasically the same as a ground block)
