I have the following represents my roof and the tree in my backyard.

The length of the roof is 90ft, it is 15ft from the center line to each
edge, (roughly 30ft),
height of roof is approx 22ft at the peak and 10ft at the gutter edge..

The tree is approximately 35ft high.

TREE

My question is: do you think it would be better to run a configuration as
say a Windom from the tree to the points on the roof (the points can be
moved) or just a simple inverted "V" and the angle of the "V" in any case is
going to be very narrow. I would be feeding either one via some Rg8x
approximately 65ft.

I would like to be able to use the ant from 160m - 6m if possible, I will be
feeding it via a tuner, and the wire is going to be #26 enameled as it can't
be seen.


Comments please.

Sorry for the repost - I was trying to get the visual dimensions correct!

Guess I'll reply to this one! ;^)

How much total length will you have? A Windom for 160 needs 260 feet.
I used a windom for a while because it was convenient, the short leg
dropped the coax directly down to my shack window. The antenna performed
okay. Depending on your lot size, you might not be able to run a full
160 meter version. would 80 meters be an okay bottom limit? Even if you
had to let the ends drop a bit, though tuning (short vs long leg) will
be a little different.

Inverted v might also be a little difficult. You might want to go for a
plain dipole.

I'm pretty dense today - getting over a nasty head cold, so I'm going to
ask a few questions.

You just have the one tree?

If so, where are you planning to hang the other end of the dipole.
Certainly an inverted V is going to need something in the middle.

With the tree at 35 feet, what is the maximum height you can hang a wire at?

It doesn't sound like a real optimum site, but don't worry, we can get
you something that will work okay.

Just some thoughts...

That #26 wire is going to be a problem no matter what type antenna you
end up with. For the longer antennas, HF, etc, it's strength is going
to be sort of limiting. It is sort of difficult to see, but it's far
from being invisible. So, if you are in one of 'those' neighborhoods
that don't like 'visible' antennas there is another choice instead of
an invisible antenna. That's using something that is very visible,
but not normally associated with antennas. The first thing that comes
to mind is a flag pole. Certainly 'do-able', and certainly not going
to be 'simple' if it covers more than one 'chunk' of HF. The 'simple'
way of 'curing' that sort of thingy is to throw money at it, to some
ridiculous point. (Wonder how 'they'ed feel about a 'commemorative'
Atlas missile monument in your yard?)

I think you might do some thinking about what's the longest, sort of
straight, 'run' you can manage using the roof ridge and tree. A few
'bends' in that 'straight' run are allowable, sort of. And then
consider various ways of 'loading' that run. One option might be a
'short' but 'long' inverted 'L', a "lazy-L"? Not exactly the best,
has it's own set of 'problems', but if it works, who cares...much.
Having 'been there, done that' at at one time or another, I really
wish you luck.
