a 10:1 balun would probably help get readings down into a range that your
analyzer can handle, assuming the 600 ohms is the real impedance.

I have built an antenna analyzer (AA-908) that reports SWR, complex
impedance, capacitance and inductance. It works fine with coax-fed
resonant antennas.

How can I use it to test a 40M double zepp with 300 ohm twinlead
feedline? I am at this point interested in finding the frequencies in
160M band at which this antenna and particular-length feedline will
propagate.

Needless to say, I see maxed out numbers almost all the time (SWR10
and impedance 600). Should I use a balun? Is there something I can
use (like a 50 ohm resistor in parallel) that will give me numbers
that I can use? What should I be looking for?
