If you are forced to use indoor antennas because of deed restrictions (HOA/CC&Rs), you may find this indoor bent vertical from KL7JR interesting. Basically, the antenna is a vertical helix wrapped around some PVC pipe.  Used with an antenna transmatch (i.e. t"tuner"), the antenna provides coverage between 10 and 20 meters.  A cheap, effective antenna for apartment dwellers.

Here's a fascinating idea for radio amateurs living in deed-restricted housing (HOAs/CC&Rs). In this video, KL7JR makes a pvc pipe-based spiral antenna capable of fitting into his 4 ft X 8 ft (1.21 m X 2.43 m) living room window.  Each bent leg is 17 ft/5.18 m long and fits with some space to share in that window frame. KL7JR describes the antenna in detail: total length of each leg of the antenna is 17 feet long (each 2 inch diameter coil, one per leg, measures about 14 feet of #14 solid insulated wire). I find the solid wire easier to work with and form the coils. I made the coils larger to better utilize the space I had (hmmm will that work?). My windows were of the new high efficiency plastic style which afforded me a lot of glass and not much metal framing to worry about interference. My LDG-100 auto tuner easily tuned 10, 12,
