I've posted here a few times. Even admitted I failed to spend adequate time to learn myself. Have asked questions due to convenience.
If you remember me. I don't have much money. Have not yet gotten on the air. My antenna possibility situation has changed also. I will be moving at the end of the month. I've been promoted. Will be working a whole lot. Not too much time for myself. I still want to get on the air.
What I have to deal with is. My boss bought me a warehouse with an apartment. I will be living in the apartment. (heck...will be working so much I'll be living there anyways) This warehouse is a typical steel sided building. Two stories high, with a peaked roof above. Can only estimate size right now. I'd say about 35 feet to the peak. About 50 feet wide. About 100 feet long.
I don't think my boss would be happy with my mounting anything on the building. I'm sure I can put up a couple tower pieces to get to roof height. Have seen them cheap, secondhand. Then I can go up higher with something light weight. I like the telescoping fiberglass poles...can get to 37 feet with one.
With lack of height...lets say 37 feet above the roof peak. I still like the idea of an inverted L. I'm open to other suggestions.
I'm looking for input on details for the inverted L. This will probably be my only HF antenna. I want 80 to 10 meters. 80/40 are the most important. 20 third most important. I still like top fed. 90 to 110 feet total. I know I can turn the vertical section. Should I stay away from the roofline? Can I just let the vertical keep going straight down toward the ground with the building blocking the bottom 14 feet?
Just basically looking for someone who would like to play with his modeling software and come up with some suggestions. I seriously don't have time to learn that software, then put it to use.
I'm still open to other suggestions.
Have thought about building a J pole. Or a vertical. I'm afraid the building blocking the bottom 35 feet to one side would rule these out. The building would only be blocking the matching section of the J pole. And the vertical? Won't be able to lay ground wires. A horizontal loop has occured to me....But gee...I don't know about setting up four small masts to support it? Would have to go around the building. Would no higher than the building work? I keep going back to the inverted L?
I will be about 12 miles north of Sioux Falls. So I'm thinking there will be a decent amount of noise from there?
I would greatly appreciate any help. Yes, I will be doing better financially after the move. Still won't be making a bunch. But should be able to afford getting on the air. I do intend to work only CW on HF bands.
