[TowerTalk] Zepp question

[Richard DiDonna]

I'm working on a simple wire solution for the yard, and am opting for a "zouble extended zepp".  Unfortuantely, the location of the antenna will be in a stand of trees about 75 feet from the house.  This would mean that with kids running around the house, a run of ladder line is not optimal.

Is there a significant penalty to using a 4:1 balun near the feedpoint?  I'm assuming not.

And, is there a particular need for 450 ohm ladder line as opposed to 300 ohm twin lead?
