Re: Need help with Partial Suck-out Theory

In cable TV we deal with rf and voltage that can be effected in different ways by the same problem. But they both have a common enemy "resistance".
A suck out and a sucked out connector can be 2 different things. When it gets cold outside and the cable retracts from temperature drop or a connector is not cut in properly it can come apart or the cable can suck out of the connector.
A suckout referred to by a sweep tech is a drop in signal in of a few or more channels in a band of channels. that can be caused by a sucked out connector.
Ok still with me?
rf and voltage can both be reduced by resistance in a bad connector or span of cable but still be present. and the higher the rf freq the more susceptible to lose it becomes.
rf signals ride on the copper cladding of the center conductor, the higher the frequency the further out the frequency rides thus suffering from more loss.
The voltage on the other hand uses the center conductor and the shield. So we can lose only the shield and lose all voltage but still have good rf until we get to the output of the next active.
So back to your suckout, Depending on what part of the cable is making contact and how much resistance is introduced by the amount of contact, the amount of copper cladding that has been striped from the center conductor, and the amount of oxidation that has occurred it can have many strange effects.

This has been your cable lesson for the day lol hope it helps.
