Why are you using a 4:1 balun with a dipole ? If it is a simple dipole
with
only one wire in each direction instead of a folded dipole the impedance
is
around 70 ohms. If you decide on a balun it should be a 1:1.
When adjusted for the lowest swr you may find that 1.4 to 1 is about as
low
as it will go if you use a 50 ohm coax.

I question my calculations for a inverted-V dipole length for 50150 and
28400 into a 4:1 balun. I think they came out too short for 200ohms
center Z
Can someone confirm my two calculations?
Thank you!
With a V, you can get the feedpoint impedance right to 50 ohms..
somewhere around 120 degrees included angle
Dittos. Radiates equally poorly in all directions though A rotatable
dipole or 2 el beam would be a simple project.
