Maximum Coaxial Feeder Length for PTP820G


Am looking to install a PTP820G system at a customer site and need to run a fair amount of internal CNT-400 feeder cable to reach the ODU installation location (~70m). As the cable carries both power and IF I was wondering what the maximum coaxial feeder run would be which would still allow the system to work? Also if this is listed in any install guides or datasheets or would it be a theoretical maximum?



From the guide... "Coaxial cable RG-223 (300 ft), Belden 9914/RG-8 (1000 ft) or equivalent".
