We have a depot under the TV tower at Chatswood Sydney NSW.  Corner of 
Pacific Hwy and Mowbray Rd.  I have had a number of work cars at that 
depot.  Camry was fine, Commodore (2 models ago) would not lock the doors 
unless the blipper was placed on the windscreen and we had a few 
commodores that 'failed to proceed'  that we put down to the high RF 
mucking up the computers.  Falcons, two of them, appear fine like the 

Correct installation probably plays a big part especially Earthing.  I 
checked my Antenna with a micro-ohm meter I was able to borrow to ensure I 
had a good ground to the body.  I used self tappers to secure the Z 
bracket to the lip of the bonnet, so they cut into the metal.

Very odd,

I drove my old VN Calais over 300K km, full of VHF gear, without a 
single problem. I would suggest that any car that has a problem has a 
problem, so to speak. What about the implications of driving past, eg, 
an FM broadcast station, an MF or HF station popping out 100kw or so?

My understanding is that motor vehicle electronics are designed to be 
pretty much bullet proof. There are liability issues here!!!!
