This may be slightly off-topic but hopefully not too much!!
I would like to build a vertical dipole for 20m with the bottom about
1m off the ground, to compliment a beam, to give me a quick
omni-directional alternative.
What are the potential problems, or issues to be aware of if I were
to take the coax feedline down the centre of the tubing that makes
the lower section of the dipole. I have seen several alternatives
where the coax is taken away from the centre of the dipole parallel
to the ground, but I would prefer not to do this.
Any thoughts gratefully received. I guess a good feedline current
choke might be a good idea at the base.
Happy New Year to everyone and thanks for the various help over the years.
73,
Dave, G3UEG
