Topband: Commercial 160 antennas?

[K4OWR]

*:::: Understand that even for the top set of guys they are not 
insulated till 17' from the tower. Insulating the others will not be all 
that easy for this once very agile 72 yo who put the tower up all by 
myself 7 years ago. Maybe change to Phillystran? I will also need more 
specific instructions on the hookup....Don't I need something called an 
"Unun" balun?**
**The radials will also be tough cause the tower is on the edge of some 
very overgrown property that would be a nightmare to move around in. **
