+1 to what Zeeb and Jezmo said.
12" is old school when talking about a modern and correct setup.
The only thing that has really changed is the quality of the newer generation ignition units. Those of us that were running ignition 15 and 20 years ago had to go through lots of things to prevent interference. Please do not think that the 2.4 equipment is a fix all to the " Old school " rules. One would be foolish to install radio equipment close to ignition and ignition power sources. Even the IBEC units have filtering designed in to make sure noise dosen't get back to the RX. IMO unless one is very familliar with RF and antenna function he should not suggest against techniques that have been proven for the past decade.
