I'm considering putting up a 80/40/20 dipole soon and I'd like to ask for some advice. There is a TON of info out there and I'm a bit confused.

I am concerned about the length of feed line that I would need to pull this off (see measurements in the attached images). Here are some details;

Shack is located on the second floor, close to where I show the feed line coming in to the house
- I need~30 feet of internal feed line
- It's ~150 feet to the treeline at the point marked on first image
- Trees are ~100 feet tall and I have the means to get lines nearly to the top.
- Presently running a Kenwood 450sat at 100w (internal autotunner)
- I have an MFJ manual tuner
- Placement in the first image would need ~180 feet feed line (150 outside 30 inside)
- Placement in the second image would need ~245 feet of feed line (215 outside 30 inside)
- I'd run rope from an eye hole bolt on the house to the trees and support the feed line with the rope
- Presently using a 9:1 unun (balun designs) and 124.5 foot #26 wire
-

The questions;
- What feed line. Talking to the locals here I'm getting massively different opinions
- Is it worth it? or should I stick with the random wire?
- if yes... fan or trap?
