[Elecraft] Non-Resonant Antennas and Chokes

[John Pierce]

I haven't read all the comments on this thread and thus may requesting
redundant info.  My antenna, for 40 mtr's, is a 67' wire up about 25'.  I
have 30' of 450 ohm ladder line connected to the end of the antenna and
bringing the antenna into my basement.  So I guess you could say that I have
a non-resonant end fed Zepp.  

 

I can check the impedance at the end of the ladder line, where one side is
the antenna and the other side is connected to a ground rod at the point of
entering the house.   I can measure the impedance of the antenna in the
basement, using Mini60 without an antenna tuner .  The ladder line is then
connected to a MFJ 926B remote antenna tuner  The tuner is fed by about 30'
of RG58 coax from  my transmitter.  When I see a reactive component to the
impedance of the ladder line, without the tuner connected, should I have
some choke inserted in one side of the ladder line or not?  Should the tuner
be able to handle the reactive component?
