I'm aware of cable loss issues, but in this case, that's just not an option. LMR-400 has low enough loss at 5 ghz that I don't see any big issue with using it, and the run really isn't all that long. The radio system is an ALIX mini-itx and it has 5 radios, plus a 2 radio ALIX board, all in one enclosure. BTW, it's a metal building, with the radios inside another heavy steel box, required to prevent nearby lightning strikes from shutting it down. ++++++++++++++++++++++++++++++ Neofast, Inc, Making internet easy 541-969-8200 509-386-4589 ++++++++++++++++++++++++++++++ From: support <mailto:[email protected]> Sent: Tuesday, January 11, 2011 11:51 AM To: WISPA General List <mailto:[email protected]> Subject: Re: [WISPA] MIMO antenna cabling... 10ft in RF cable is a Bad Idea I would put you board in a weather proof box and put it next to your antennas On 1/11/2011 1:16 PM, MDK wrote: 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!
