Antenna mounting/installation

What would be the minimum distance the antennas should be apart ?

Andy, ideally, they should not be closer than about 1/2 wavelength, but this is not possible with the 27MHz AM. If you can do it, opposite ends of the bullbar would be your best compromise. (1/2 wavelength at 470MHz is about 320mm, but at 27MHz, this is about 5.5metres). Your system will work if you put the antennas close together, but with diminshed performance, even if you readjust for vswr. I see lots of installations where the antennas are about 150mm apart, and I guess they work.
Running the coax cables close together should introduce no interference.

I read somewhere a minimum of 60cm apart, dont remeber where I read it. Bottom line further apart the better.

Chris, just a quick question. Which one is the ABS grommet? Have a GU with out ABS. Thanks in advance.

Ok, when you are looking inside the engine bay, stick your head down near the auxilary battery on the passenger side. You will see a gromet there that has some cables coming out from it, these will be clipped-up out of the way on the wheel-well.

From within the car, remove the door scuff-plate by pushing your fingers into the carpet at one side and pulling directly up, fairly firmly. Don't go too far, otherwise you will break the plastic! Remove the kick panel, the carpet screws from the foot well and pull the carpet out of the way. Now you can remove the grommet, the cables and everything from within the grommet. I pulled the wires from the the connectors and did them back up again, alternatively, you can cut and tape them up out of the way, as they were for the ABS system that you don't have. If you want to keep everything intact, simply untape the grommet and force your cabling through.

A hint... If you want to make it easy, get some KY gel and smear it on the cable. This is a water-based lubricant and is safe for use on the cables, it simply dires out and goes into a fine powder, that can't damage the cabling.
