Any cable length is feasible - provided you don't mind losing the range. Every dB of cable attenuation costs you some kilometers of the maximum distance the LoRa transmitters can be away from your antenna. From attenuation point of view alone, you could replace this particular 1 m cable with a thicker one that could be proportionally longer for the same attenuation, but you'd have tough time arranging it mechanically. So think about a very short (10-15 cm) cable at the wAP end, connected to a longer 1/4" or even 1/2" one.
The product pages do not specify the gains of the antennas (neither the internal one nor the external one) nor the attenuation of the cable, so it is hard to say what amount of cable attenuation completely erases the advantage of the external antenna as compared to the internal one if they were placed at the same spot. That 1 m cable should have less than 0.5 dB attenuation at 860 MHz.
Given that the wAP is designed for outdoor installation, why is a 1 m cable too short for your purpose?
