content: Hi All,I hope this is the right place, if not feel free to move it.I (finally) start will installing (sat) coax cable in my house (rebuilding).I’m in pretty rural area. My internet is now LTE, but I expect in the coming years 5G will become available.Looking for some advise which cable type to install (these go under floor in to the wall))?What would be the “correct” parameters to look for: 50 to 75 ohm? LMR ? (200/240/400/…) ?Some help is much appreciated, thanks!

content: I'd recommend Kathrein KALCD 110+ or something similar. It has to be 75 Ohm impedance. Get something that is at least triple shielded.I'd also recommend putting the coax into conduit so you can relatively easily change it if necessary. In DE that is a must for all low voltage, data and coax cables, don't know about NL.

content: Bonjour 5G power is so low and mm waves so easily blocked, that the coax is irrelevant.We use Belden RG/59/U 75 Ohm for al cable/sat/CATV.For very long runs the much thicker RG/6U has lower loss.The widest BW cable si Belden 1494A, RG/6U, 6 GHz.https://catalog.belden.com/index.cfm?event=pd&p=PF_1694ATo obtain specified losses and BW use the Belden connectors and crimp tools.Bon chanceJOn

content: Most likely a fixed 5G modem isn't going to have a coax connection at all but rather the unit mounts outside and is connected by Ethernet. Starlink dishes work the same way.

content: OKare you talking about 5G as in 5 th generation phone or sending high dater rates as when using a 5 G network or 5 GHz radio interferenceas 5 G uses meany frequencies in its architecture including the ones used for 4 G5 GHz radio can get into low grade coax so depending on its useif not going to be flexed or moved then coax with a foil screen is goodif the coax is to be moved or bashed about by the elements then screen over screen should be consideredRun lengths should be considered and connectors can be the issue strongly suggest not screw on but ether solder on or crimp best being TNC or N connectorsregarding the type and make of coax others have already given good suggestionsbut amusing you are just talking about low dater rates ( below 50 Meg bite ) from your modem then coax will most probably not be usedand a screened cat cable should be considered not forgetting to use the correct plugs for screened cable otherwise the screen will not be connectedThe use of conduit is a good suggestion makes things future prof , use the long sweeping bends and no T joints or hidden boxes also metal boxes are better for screeningPaul

content: Quote from: NiHaoMike on January 25, 2022, 11:27:32 pmI understand. This is more about the interference 5G could cause on my TV/Sat cables.The general consensus is to use a 3 shielded coax cable (for blocking 5G interference).Thanks.

content: Keeping in mind 5G is not about just cellular technologies, but goes from low UHF to high SHF, the answer is not that simple. I would guess, unless you are very close to the source of transmission, just about any coax suitable for use in satellite TV will be good enough. If you are using quad shielded RG6 now, that will be sufficient.

content: put a 5G filter on it instead of trying to go crazy with shielding, its not a VNA, your TV signal is digital.
