Sorry for the long post before I start.
I haven’t been paying full attention here but assume you are having interference issues in the receiver?
Ferrite cores are a black art & are a theory for RF noise reduction, but really not proven, essentially what you are doing by wrapping a cable around a ferrite core is just reducing it’s length as an antenna, you could achieve the same result, folding it in very short lengths & tying it or wrapping it around a wooden stick.
Ferrite cores essentially are used for various magnetic reasons especially reducing eddy currents in electrical transformers or any electrical charged wound cable.
Nautel a major RF transmitter manufacturer even supplies ferrite toroids when you buy a transmitter, that you’re supposed to run the RF output coax through, so it can reduce the Eddie currents & straighten the run of the electrons in the cable & give you a better signal output.
Unless the client specifically asks for toroids to be installed, I never put them on any transmitter installation & neither do any of the other broadcast techs I know, because there’s actually no proven, in real life improvement or change to the signal having them there or not, other than maybe changing the signal for 10cm as it passes through them, the signal & electrons will do whatever the hell they want, as it travels though the other 300 meters of cable going up the tower to the antenna & then maybe 100km through the air to the receiver.
Ferrite cores are used in small AM radios, as wrapping the antenna wire around them using the ferrites magnetic properties actually increases the signal strength like a passive amplifier, so you can use a smaller AM antenna in a smaller receiver, in that case it makes perfect sense as is proven positive, as far as RF interference suppression, it’s actually making the wire (unwanted antenna) smaller that’s making the difference to the level of interference, as the wire becomes less efficient at being an antenna for the unwanted RF.
As for using Cat. 6 cables to reduce unwanted interference that’s not affecting the data transfer (i.e making more packet loss or error in the data) but in the actual radio receiver (SDR), then you’re barking up the wrong tree.
Cat. 6 cables are different to Cat.5e only in the amount of data they can transfer (bandwidth) due to Cat. 6 having the internal pairs twisted more tightly (more twists per meter) than in Cat. 5e & that’s mostly to reduce interference between the pairs & help reduce crosstalk & a few other things.
In Cat. 5e, Cat. 6 & upwards cables, each pair is twisted at different rates to also help with that interference between pairs & when you split the pairs terminating the cables, depending if you use the A or B specification will depend if the cable will better upload or download data, it really doesn’t have anything to do with external interference, it’ll still act like an antenna to external RF unless you use shielded cables, & then if you use shielded cables, make sure the shielding is only terminated at one end & grounded at the same point, don’t terminate the shielding at both ends & don’t ground the shielding at multiple points/locations, otherwise it’ll become an even greater antenna than just the twisted pairs of an unshielded cable.
Great idea. Though in my case & only specific to my router, upgrading the cat 5 patch cables from the router to CAT6A S/FTP made a dramatic noise reduction on the VHF band, far better than ferrite chokes. I think CAT 8 by default is also S/FTP, but overkill for most home installations. Chokes are easy to use & more turns the better generally.
