Kevin: Looked at your place. Hopefully, you have a long weekend!
Got some ideas on your Doublet! Let me know we'll chat.
You've got a GOOD spot! Nice horizon distance in several directions. You should do well!
All the Best
Gary
PS: That 40/15m Vertical should do Nicely also!!!

Hiya Gary
It’s been a few days since I posted, I’ve been a bit busy.
I did run another dipole, I made it 130 foot. 65 each leg. I got the feedpoint about 35 feet. The ends come too close to the ground though, I need to get it higher.
But the good news is, it tuned to 80 meter and worked good. I made several contacts. But the bad news is, it tunes to 40 also but the vertical out performs it on 40 by far.
So right now, I’m switched my back and forth. I ordered the swivel mount from DX Engineering, it will be here today. I am redoing the vertical since it performs so well.
But the dipole, I think I need to get it higher. 35 feet at the feedpoint is still too low. ,

OK GREAT Kevin: Remember conditions!
Here are a couple of thoughts, looking at your location. If you can get a rope over the limb of that tree close to your tower up about where the feed point of the 40m dipole is. (?). Then think about that small tree close to the big road, so the rope comes out of the top. (so not to restrict access)...look to stretch the Doublet from that point to the other rope...Don't worry that the center does not fall next to the rope. You are going to put a "slip point there" So sloping toward the small tree the up to the High point. Then whatever is left of the Doublet can pull toward the house or down to the ground (where ever)
This may be hard to visualize but think about it. Go some other thoughts also. OK got to run to Home Depot with XYL to get "stuff" for new TV antenna tower going up!
Think about this be back later...we'll chat some more.

Wow that’s crazy how you can survey my property like that.
Not sure if I mentioned it or not, but I also own the lot behind me. It’s unkept, it was that way when we purchased it. I hope by next year to have it excavated and make it part of the yard. But for now, I can do anything I want there.
Also this small town doesn’t enforce code. You can run extension cords through your walls and they could care less lol. A bad thing, but when it comes to antennas. A good thing for me anyway.
The dipole that I have up works pretty good for now. My ground mounted vertical worked much better than anticipated, so much so that I spent the entire day yesterday digging and pouring a foundation to make it a permanent install. It may not be for another 2 weeks before I complete it. I did order one of those DX Engineer lay down masts that you guys suggested. The post is set and tomorrow I’ll be attaching the mount. After this project is complete, I will be turning my attention to the dipole.
Which leads me to some new questions if you or anybody has an answer for.
1. My ground mounted vertical, I would like to call it an all band vertical but instead I’m going to call it an “any band I can get cross my fingers verticals ”. It’s only about 15 feet outside my radio. I have ladder line, and I was hoping to use that on this. But my trailer is metal. I know about the various methods to get ladder line inside the shack,,,,but my question is, should I bother? It’s so close to my house that perhaps I’m better off just using regular coaxial cable where I can bury it inside PVC pipe and run it in the ground so it’s not in the way? Or is ladder line still my best hope? I am using a Balun and a tuner.
2. My vertical is going to be tuned for 40 meters. But I had a curious thought. What if I used galvanized cable for one of the guy wires at 33 feet, running it towards the tree in a horizontal run from the vertical, then converted it to Dacron. In hopes that this would add 33 feet to my antenna and maybe I can get lucky and tune and 80 meters also. Or is this just a dumb idea?
3. I am putting a grounding rod at the base of the verticals and grounding the radial ring to it. I understand this is for RF ground? Should I run a ground wire off of each piece of my equipment inside my house to the same grounding rod? It would be a body 15 foot run of wire. Or should I pound a new grounding rod closer to my house and then just run a wire between the two?
Should I run a ground wire off of each piece of my equipment inside my house to the same grounding rod? It would be a lengthy 15 foot run of wire. Or should I pound a new grounding rod closer to my house and then just run a wire between the two?
Hopefully my questions are not confusing

I have never used this EXACT configuration. I have however seen antennas done in a similar fashion to be used Multi-banded.
This is a variation of the Inverted "L" antenna.
The 2 short wires act like a "Top Hat" and double as support.
There could be one or more (3-4 etc.)
Then fed with Ladder Line /300 ohm etc.
The one side of twin lead goes to the vertical element, the other side to the radial field/counterpoise.
Then matched with your new manual tuner, and connected on the Balanced line output terminals just as your Doublet does.
When using this antenna I would ground the Doublet to your station ground block this should keep it from picking up RF and bringing it back into the shack with no termination on it.
I would do both rods, Kevin. Then tie both together with the biggest gauge cable you have, or twist multiple strands together of bare copper wire. (3-4 strands of like # 10-12)
This does not need to be in conduit, just simply buried slightly or even just pegged to dirt so it will not get disturbed or damaged.
You must have figured out a method to get your twin-lead out to your doublet. I would be interested to know what you used.
The twin lead going to the vertical should be kept off the ground like a foot or so just so nothing comes in contact with it.
I have never tried to bury twin-lead in conduit, but guess it would work, as long as it did not get water inside the conduit or any other contaminant (dirt etc.)
Maybe someone else has done so with success?
So here's the VERY CRUDE
drawing I did as a suggestion on the antenna.There may be others that have ideas also. I have done this similar type of set-up during Field Day weekends and done well with it on 80/40/20 meters.
So there are a few thoughts.
All the Best

I think for the ladder line going through the wall it is going to be easiest if I use two pieces of coax through grommets going straight through and trying the braids together whilst using the center electrodes as each ladder electrode, I’m sure you are aware of this method, I’ve read several different websites that mentioned this method.
If I go any other route it’s going to be a major undertaking

I was going to come off the mast about 3/4 of the way up with the galvanized guy wire.
Perhaps I should just follow this diagram you posted and come off the top
