Thanks! Very interesting, imay well give it a go upgrading the cable etc. From quick look doesn't look like rocket science wiring...Hi
You can change the cable on the antenna, as long as its 50 ohms, and also for the desired frequency range, however cutting the cable close to the back of the antenna and putting in connectors will introduce insertion loss and provide a weak point for water ingress etc. Best results would be obtained if you were to un-solder the existing cable and replace directly onto the antenna board inside, but this will mean opening the antenna enclosure up, which is not for everyone.
Have a look at some of the online cable loss calculators.

Stick in the cable type and length you have (or the length you think you need, and see the difference on each of the bands)... you will be surprised at how much less loss better quality cables have in comparison to the cheaper cables that comes with these off the shelf 4G antennas. LMR-400 (RG-8) is a good compromise for an upgrade, for flexibility and performance.
As Gavin said, for best results, stick the Router up next to the Antenna in a IP67 Enclosure and power it via PoE over Cat5e/Cat 6 (if its capable) and keep the coax as short as possible. Or in
One question on your recc for cable I've found following which I assume is a good cable. Their SMA male is £5 a pop vs £10 for loads on amazon...
Is there a real difference, or would this cable not fit the amazon ones?
