[Antennas] Input Needed

2003年5月14日 15:15:50 +0000

In an attempt to build the ultimate Multiband DX Antenna, I need to make a 
decision on which Balun to use. My biggest concern is efficiency because I 
want DXCC QRP! The Atenna in question is a Colinear Dipole made entirely of 
open wire feed line, 80 feet in the air. By using the open wire for the 
elements of the Dipole, the arms need only be 42 feet apiece. I have three 
different Baluns available and all seem to work! Balun #1 is a Standard 
Torroidal 4:1. Balun #2 is a "Choke Balun of 12 turns of RG-59 on a T-200 
Core, Balun #3 is an AMIDON Bead Balun on a length of RG-213. Which one 
shoul I use and why?
Please respond; this is my SECOND attempt on this reflector with zero useful 
response the first time.
 "Communications" is a People skill, the rest is technology.
