If you have a tall tree on your property, you may want to try this antenna.  As Stan Gibilisco (W1GV) explains, this multiband HF antenna can be used where space is at a premium.  Each leg of the dipole should be at least a 1/4 wavelength at your lowest frequency of use.  An antenna transmatch (i.e. "tuner") and ladder line will permit multiband use.  Try this simple antenna and "work DX on a budget."

Simple Ham Radio Antennas--Vertical Dipole in Tree

If you're having trouble viewing this video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=RI2_T-LeYEU. This is post #990 in a continuing series of Simple Ham Radio Antennas.  Here's another dipole antenna for those lacking the space to install a full-length horizontal HF dipole.  This antenna is vertical dipole fed with 450 ohm ladder line and arranged so that each element is suspended from a tall support such as a tree or telescoping fiberglass mast.   Stan Gibilisco (W1GV) does a good job of explaining the theory, construction, and use of this dipole variant. If the dipole is cut for the lowest frequency of operation and fed with ladder line, television twin lead, or  homemade balanced feeders, you will have a cheap, easily made dipole capable of covering several HF amateur radio bands .  An antenna transmatch (i.e. "tuner") with a 4:1 current balun is needed to match the feed line impedance to the impedance of
