[Elecraft] Single Band 40 Meter Dipole

[Mike WA8BXN]

A table I looked at suggested that on 7 MHz loss for RG8X would be less than
1 db for a 100 foot run of it. When dealing with a resonant dipole on the
lower HF bands feedline loss is not a big issue. I would not consider using
open wire feed for such an antenna (unless I wanted to operate on
non-resonant bands with that same antenna). I'm not sure I would even bother
with any sort of choke or balun. I would not expect RF in the shack or noise
problems. If those issues did appear, then I might look into chokes/baluns.
