Topband: 160 meter elevated vertical

[Cqtestk4xs at aol.com]

I'll be putting up a T-top elevated vertical for 160 in the next couple of  
days. The baser will be around 60 ft above ground and the Tee (about 40 
feet  long will be at about 170-180 ft...depending on the caternary sag. There 
will be  4 radials at 90 degrees to each other.

Question: Any type of balun necessary with this? Or is it good to go. I'm  
using RG58 to feed it to keep the weight low on the caternary to avoid say 
but  could wind something on a four inch PVC.
