[TowerTalk] Balun or Not To Balun

[k7mks at comcast.net]

My previous HF antenna system was HB 2" ladder line connected to a 275W Match Box and exiting the flat shack roof thru 2 behive feed feed thru insulators. Once outside the ladder line headed for a 1/2wl 80 80m. Worked fine for years. 

It has been suggested that I eliminate the roof feed thru unsulators and run 7-8 feet coax, thru a side wall to outside or eliminate the MBox and run the coax directly to a 4:i balun outside. and then to ladder line to the antenna.. Running coax or 2 wall mounted insulators will allow me to avoid puncturing the new roof over the shack 


What would you do? Stay the way it was, which performed nicely, or use coax to get outside to a balun and then HB ladder line. 

Thanks, joe k7mks
