Ron,

An inverted V has a different radiation pattern than a vertical. Plus, the
multiple dipoles will interact with each other regarding adjustment.

I could discuss it further but since your email address is not valid, I didn't
want to spend the bandwidth here, hi. I guess deleting the "dot" might get the
right address but I'm a little pressed for time to play guessing games right
now, hi.

Evan,

If I thought I would be getting Email response to this post, I would
have included a good address, sorry.

I have decided that I will do a little experimentation. I have a
tripod on the back dormer with a 2m ground plane that is only 5 feet
above the roof. I can use that for an easy access connection point and
run a few dipoles sloping down from there. I will start with 40, 30
and 15 and see what happens. If that works, I will add more bands.
Once I have the lengths worked out, I can raise the center point.

I would be interested in any idea you have on the subject.

When trimming multiple dipoles on one feedline, start with the lowest
frequency one first. It may take more than one iteration. Best if you can
run EZNEC on it first to get in the ballpark. My gut feeling is to not put
the wires for adjacent bands next to each other.
