I have a project to setup a full wave 160 m dipole.
My questions are:
Is there some trick to build such antenna?
Each leg lenght is simply, say, 300/(2x1.82)MHz x
cable correction factor?
How long should be the separator?
What cable diameter should be used if I operate 100 W?
I intend to use a 50 ohm coax without ballon as
feedline. Another possibility is to use open line
(paralel), because there will be no metals around to
interfere. But in this case I do not know how to match
the impedance.
The details follows:
Where?
There is a nice place where I use to go about every
two or three months. There is a hill forming an "U",
whose distance between the extrem borders is 150-170
m. All the top is relatively flat, so one can walk
around relatively ease. Its height is not known for
me, but I asure it is pretty high, I guess more than
100 m. I will check the topographical chart to get a
more exact value.
How?
I intend to park my car equipped with a FT100D at some
distance bellow the botton of the "U". A little (1 m
height) mast will be fixed on the left side of the "U"
and another on the right side. These will sustain the
ends of the dipole. I do this all from the top of the
hill.
The result will be a full wave dipole over more than a
half wave distance from the ground.
When?
This is a good question. The place is somewhat remote
and I wish to choose a good propagation time.
So, your the opinions about this plan are welcome. I
appreciate the replies.
