Antenna questions regarding on receivers in rack

I'm in the process of configuring the the main rack for my band.  I have three XD-V70 receivers I plan on mounting in the middle of a 14 space rack.  I have several questions regarding best practices with regard to antennas on these units:

 

1. Would it be ok to mount the two antennas to each unit and have them all point inward toward parallel to the receivers?

2. Should I daisy chain them and have one pair of antennas out front pointing upward, yet not above the top of the rack?

3. What if I get some LMR195 cable and make some 6' extensions for the antenna pair and mount them up about 7'?

4. At what point do I stop playing around with these configurations and just go with a set of P180 antennas?

 

Other things to keep in mind... I may have a wireless router in the rack operating at 5Ghz tied to the mixer.  Will this affect the receivers?

I'll also have a 2.4Ghz wireless DMX transmitter in the rack... again, will this affect the receivers?

Option 1: Not really, no. The antennae should ideally be 45 degrees either side of vertical - pointing inwards won't give you decent diversity reception.

Option 2: Daisy chain - yes. Line of sight is important so if the front of the rack is facing towards where the transmitters are, you might be alright.

Option 3: Now we're talking. Getting the antennae up clear away from the rack is good. Get some distance between them too - again for diversity reception.

Option 4: Good option.

 

Other transmitters in close proximity to your receivers is a bad idea - even if they're on different frequencies they can still swamp the RF input stage which will wipe out your reception. If you've remoted your antennae (option 3 / 4), you might get away with it but I'd still want to keep that DMX TX well away.

I agree with Sheriton, but would question the distance you are talking about from TX to RX first. That may not be necessary.

 

Never place a wireless system in close proximity to a router, your DMX tranceiver, CD player, Digital recorder, or any other digital device that gives off possible RF. I always suggest investing in a separate case for wireless, even if a soft case. 

 

I don't like wireless DMX at all unless absolutely necessary. They are slow and can give erroneous signals to your lights. Run a cable if at all possible.
