Shorter the better is generally the rule of thumb with radio signals and coax cable. Basically to make up for the increased attenuation (loss) due to longer cables you need to increase the size (thickness) of the cable, which makes it expensive and more cumbersome.How long can the 4G antenna cables be? At our site 15 m would be handy as we have just had foil insulation in the roof space which will block most signals, and the flint walls have a similar effect.
Ultimately without an amp, and long lengths of coaxial back to your radio/receiver, you simply end up losing whatever you’ve gained, literally by fitting a higher gain external antenna.
This is why most standard dual polarised LTE panel or directional antennas that come with their own coax built in, only really come with 5 metres of quite thin dual coax cable.
Of course you can get (more expensive almost pro) antennas where you can fit your own separate, thicker coax of whatever length you choose, however as said you must be careful not to cut off your nose to spite your face. In that all the gain gets soaked up by the extra loss in the
