In MIMO, Dis-similar Cable length to the dual pol feeds CAN be a problem. Both cables should be the exact same length, or as close as you can make them.
This should not be a problem for a 10ft cable. Simply crimp the indoor connector first, since ends terminated really close to each other. Have second cable follow the first cable (maybe even zip tie it to it) and then outside cut the second cable at the point where it reaches the first cable's end. It means not totally using pre-made cables, and having to crimp the outdoor connector manually. Use Ezy connectors to ease abilit to crimp cables up on a roof without the need for a soldering iron.

I'm in the position of wanting to test the Star-OS MIMO mode, and it occurs to me that connecting an antenna through a few feet of cable may have some pitfalls... I'm going to use dual polarity antennas, and so I'm wondering if I need to use very closely matching cable lengths for the cables that connect the radio to the wire? The board / radio are inside the building, and the antennas will be about 10 feet away, or so. Is this an issue to be concerned about? Anyone know? ++++++++++++++++++++++++++++++ Neofast, Inc, Making internet easy 541-969-8200 509-386-4589 ++++++++++++++++++++++++++++++ ------------------------------------------------------------------------------ -------------------------------------------------------------------------------- WISPA Wants You!
