Currently I run a 84 foot random wire at my home QTH. It is setup as a sloper, running from my deck to the tree line at 60 ft, with about 15 ft of wire dropping down. A "sideways 7" design. With a 9:1 balun and tuner I can work 160-10m.
For easy deployment I have a line run up in a tree with two 90° PVC pipes making a U that acts as a pulley. This keeps the line in the tree from rubbing on the branch and wearing out.
At my previous QTH I lived in a town home so I could not have anything permanent. I would setup a 20m ground plane vertical with half a dozen radials on the ground. Setup on Thursday, torn down by Monday to not have the grounds keepers run it over with the lawn mower.
When I first got my ticket I was living in an apartment. I mostly worked repeaters and portable HF at the local parks. But when I wanted to work from home I had to deploy something stealth.
A super short 20m Dipole with massive coils (img)
Hidden apartment mast, can you see it? (img)
I created a super narrow band 20m dipole. At that point I was only doing SSB so I created the dipole specifically for the middle of 20m voice. I created a PVC mast that hooked out my window, into the gutter on the roof and then up another 4 feet. The mast was covered in duct tape the colors of the siding and the shingles so from the street you couldn't see it.
I also ran a 10m inverted V from my wall when working QRP digital modes.
