What is the difference between LMR® 400 and LMR® 600 cable?

LMR® 600 is a thicker cable than the LMR® 400.

You typically use LMR® 400 when going runs from 5ft to 40ft.

Anything 50ft and above, you want to use LMR® 600.

Because the cables will add loss to your signal, using the thicker LMR® 600 will reduce the loss when reaching those longer cable lengths.
