I want to extend coaxial cable between Maritime 40G antenna and MAX BR2 Pro by LMR-195.
Is there a recommended length limit for using LMR-195?

Hi Tim,

I would not recommend using cables longer than 5m (16ft). The reason is the signal attenuation. The longer the cable the higher the signal loss and the worse the performance (throughput, range, etc).

Here is a link to calculate LMR-195 cable attenuation for different cable length and different frequency. It would be good not to exceed ~3dB attenuation.
