2M belden 9913 LMR400 ultra low loss drop-in RG213 coax
This is a 2 metre length of double screened High Flex Belden 9913F low loss 50 Ohm coaxial cable. There are N connectors at both ends which seem firmly fitted.
A common use is for UHF and microwave interconnects after a rigid coax downlead.
There are significant benefits from VHF upwards. Belden 9913 is similar to LMR 400 and both are markedly lower loss than RG213 and RG8.
The diameter is the same as RG213 types and 9913 is about the best drop-in upgrade. There is a coax loss calculator here: http://www.ocarc.ca/coax.htm.
Your transmission system is only as strong as its weakest link. Using cheap or inferior cable can severely limit your broadcast power and range. The best way to determine if a cable is right for your application is to make sure that it has a low dB loss at your frequency and a high velocity factor. Belden 9913 cable is beyond compare.
