An amazing amount of materials can be used to make HF antennas.  In this video from NC4FB and KI4PMT, we see an old VHF/UHF construction process applied to the amateur radio HF bands--namely, using inexpensive steel tape measures to make horizontal dipole elements. According the description of this innovative HF antenna, the tape measure variant performs well on all amateur bands between 6 and 40 meters.

Antenna design and experiments are part of the challenge and fun of Amateur/Ham Radio.  You don't need lots of cash to enjoy the "radio art" if you're willing to use your imagination and a little creativity. "Ham Radio Concepts" says the intent of the project " is to show the newcomer or the seasoned operator WHY it is fun to experiment and homebrew. This

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.

One of the major challenges to using the 630 meter amateur radio band, is the shortage of commercially produced transmitters, receivers, antennas, and loading coils.  Although there are several companies that market these devices, it may be best to experiment with something you build yourself. In this video from Kevin Loughin (KB9RLW), we see a fairly simple way to "homebrew" a "bucket variometer" that will get you on the 630 meter band. Kevin takes us step-by-step from theoretical design to finished product.  According to Kevin, the device works well and will give you many hours to explore one of our newer bands.
