[TowerTalk] ground wire thoughts

[w5jmw at towerfarm.net]

OK,it is somewhat winter hr.I am getting ready to lay ground radials 
while the grass is dead for the winter.My antenna farm is on a square 
acre.I have a tower in the sw corner.A sal in the mid north.Plans for a 
80 phased array along the east side.What I am wanting to do ie to run 
radials from corner to corner.That is to say from ne to sw and from nw 
to south east.Initially run these then go from side to side.The radials 
will be jouned in the middla by a split bolt to a ground rod....I plan 
on using the radial for all the antennas if possible.My question...First 
Can I do this ?
Question 2 does the radial foeld need to be at the base of a 
antenna.Could i run a radial to the ground screen and sue the 
screen.Which is what I envision after all is run...Pros and cons please 
before I start.If I use independent radials they WILL cross....Thoughts 
on this please...73 john W5JMW.a little pistol trying to grow..
