Here are two other ideas to consider, probably neither is a great idea, but should work. How about installing a good mobile antenna on one of your cars. If your subdivision does not prevent this. Then run a small stealth coax out to the car. Configure it with some type of break away connection, so if the car accidently gets driven, no problem. Install something better and bigger than a ham stick. Performance on 20, and 17 should be good, 15, 12, and 10 meters should be excellent, and 40 and 30 meters should be useable, especially if the antenna is at least something like 8 feet or longer and has a low loss loading coil, preferably at least several feet above the base. Another idea I have considered if I ever need to live in civilization rather than out here in rural Alaska is to buy one of the "portable" basketball hoop supports which I seem to see at about every third house in HOA developments in AZ, CA, etc. Put it in the driveway, install some hidden radials and an automatic antenna tuner beside your driveway where you have the basketball thing. I have not measured or modeled them, but if you electrically tied everything in the structure might be equivalent to say a 10 or 12 foot wire, which is probably long enough to work moderately OK on 20 through 10 meters with any good tuner. I have not tried either of these schemes. Please do consider going to a local park instead. Often when we travel or visit outside of Alaska, I just send the girls (wife, daughter, and granddaughter) off on a shopping expedition or visit to a spa for the day while I sit a picnic bench in a park and operate my portable equipment. It does get a bit rough at times like north of the Arctic circle in Norway in the winter, or on a hot summer day in AZ. Also many parks close at sundown or before 10 PM. Even a typical urban city park only a hundred meters or so from houses, usually has low or very low receive noise levels. Low power (probably CW) outdoor operation does not appeal to everyone. When my grandkids were young, often we took them to the park where they would play on the playground or skateboard while I played radio and my wife would knit, read, or play with the grandkids. Warning, with the present sunspot cycle status being what it is, my park expeditions over the last 5 years have not been as productive as in past decades, both in the "lower 48" and in the UK and Europe, so do not expect a 100 percent success rate.
