Dipole green banana
Greetings,
FTposter...pretty new at this.
I 've decided to build a dipole antenna to listen to the railroad band. Receive only.
Using two aluminum rods (14.33" according to calc's.)
2 questions:
1.) Do I use 50-ohm or 75-ohm coax?
2.) Do I need a balun in between the coax and the tenna (1:1, 1:4 ???).
Probably going in the attic or at least that high. Ceiling is vaulted were the attic stops. Maybe up toward the ceiling. Can't put it outside (zoning restrictions, etc..etc..).
I'm sure this thread probably exist somewhere on the forum but any help would be greatly appreciated.
