[TowerTalk] 2 Element Quad and Baluns

[Scott McClements]

Daniel,

Are you an ARRL member? If so :

If not the ARRL Antenna Book also has details on a 2 element cubical
quad.  Since you are apparently starting from scratch, I suggest you
build from one of these aforementioned  plans and checkout
http://www.cebik.com/ for more 2 element quad ideas.  What exact
design you use will dictate whether or not you will need to use a 2:1
transformer and you might not need them on every band. As has been
said again and again, do not bother to build this quad and combine all
the feedpoints on one feedline, you must use a switchbox and feed each
band individually (one coax per band)  for this to be a worthwhile
project.

I now have a new question. I am trying to build a two element 5 band (20-10m) quad, it will be on about a 10' boom. I have read some places that say you do not need a balun, and others that say you will need a 2:1 balun if you want to connect all the coaxes to one feed (or a relay.) Can you just feed these antennas to one SO-239 without a Balun?
