[TowerTalk] Radial question

[Phil Snyder]

If someone knows of a better reflector/avenue for this question please 
let me know.

I am going to put up an HF9V this fall out back. I also plan to put up 
some type of inverted L for 160. I can find all kinds of theories about 
radials coming from one antenna being crossed, not crossed. Some say it 
doesn't matter some say it is verboten. My question is radials from 2 
different antennas. I believe all my radials will be insulated so bare 
wire to bare wire shouldn't be a concern. Can I just let them over lap 
where ever they do or do I need to plan this out with a surveyor, 
transit and GPS.

Thanks
Phil
