Don't let HOAs and CC&Rs stop you from enjoying Amateur Radio.  With a bit of imagination, some speaker wire, a 9:1 UNUN balun, and an antenna "tuner", you can get on the air just like KK6FUT does.

KK6FUT uses 14.5 feet/4.42 meters of #22 speaker wire running into a tree in his front yard.  The 9:1 UNUN is based on a design from the Emergency Radio Club of Honolulu (EARC) and does a good job of matching KK6FUT's rig to the relatively short wire antenna.  According to KK6FUT, the best performance can be found on 15 and 10 meters, although contacts can be made on 40, 30, 20, and 17 meters.  You may have to add a few feet/meters to make the antenna more efficient on 40, 30, 20, and 17 meters.  A simple ground radial/counterpoise system will keep rfi out of your shack.  A compromise antenna is better than no antenna.
