Richard,

On 75m and 40m, I am interested in NVIS. For 20m and above, DX.

The soil is sand - high desert sand. I am also on a hile. On the side with the
feedpoint, we have a small walking space about 20ft from the antenna. After
the walk space, a drop off occurrs of about 40 feet to the next street. The
next side will have one of the eaves and be 15' high then go up the eaves to
about 25' or 30' from the ground, then back down to 15'. The front will be
about 15 feet high. The next side will be like the first one with eaves, and
then back to the backside of the house. I am guessing on the heights.

I am wondering about the 450 ohm feedline. It would pass near (less than a
foot) my pc on the way to the rig and tuner. Would it cause RFI?

I also have an offer of 4 5ft mast. Would it help to use the mast to push the
antenna up a litte more?

On the frount of the house, I am planning on running the wire under a pvc rain
gutter. We have the power feedline coming in from the pole to the service at
the front.
