[Elecraft] K2 and wire antenna

  <cut> My HF antenna at present is an inverted V configuration hung 
from one of the trees at about 40 feet off the ground (also the yard 
is not level, there are several slopes) and the end points tied to 
another tree on one side of the yard and a fence on the other 
side.  The antenna was cut for 40 meters.  The feed line is an 
unknown length of 300 ohm television twin lead coming into the attic 
then through a closet to the radio.

Would the K2 with an internal ATU be able to work with this 
antenna/feed line combination?

Thank you,

JIm,

I have had very good performance from an inverted V hanging from an 
oak tree at 30 feet to the center with my K2. My inverted V is 
actually a three band unit with wires cut for 40, 30 and 20 meters 
all fed at the center with 50 ohm coax. I used an antenna analyzer to 
trim the wires, starting with the 40 meter section first, for minimum 
SWR at my operating frequencies. I had very little problem getting a 
match for each band and I did not need an antenna tuner. The 40 meter 
section can also be used for 15 meters but I found that the match was 
up near the top of the band and an antenna tuner (I use the KAT2) is 
needed to prevent the K2 from cutting back on the power due to the 
higher SWR at the lower end of the band.
