Comment: Although this antenna is a bit complicated, you may want to consider G4IZH's design if you can use no other antenna on your lot.  The "aerial" requires a bit of technical skill, but the rewards of completing this project far outweigh its challenges. G4IZH says the antenna covers the 20, 17, 15, 12, and 10 meter Amateur Radio bands (14 MHz to 29.7 MHz) with a 1:1 SWR throughout the tuning range.  Each construction step is illustrated by excellent photographs and helpful suggestions. Like any compromised antenna, there are limitations that should be considered: "The main problem with mag loops is that they are very high Q and need to be re tuned even for a relatively small change in frequency so a motorised tuning capacitor ar

Comment: If you have some basic plumbing tools and some experience in soldering copper pipe, then this homebrew magnetic loop antenna may be what you need to operate in stealth mode without your neighbors or landlord noticing your antenna. According to G4IZH, this sturdy magnetic loop antenna (aerial) covers the 20, 17, 15, 12, and 10 meter bands (14 through 29.7 MHz) and can be made from commonly available materials from the nearest plumbing or building supply store. G4IZH supplies a complete set of instructions and photos to help you make this near professional quality antenna. Of course, there are limitations and a few cautions attached to this antenna project: "The main problem with mag loops is that they are very high Q and need to be re tuned even
