If you want multiband HF coverage and can only erect one antenna for that purpose, you may want to consider the classic "Fan Dipole" which has served the Amateur Radio community for many decades.

In this post, Dave (WB4IUY) describes a fan dipole created by YC8PVU which can cover several HF Amateur Radio bands with just one antenna using a single 50 ohm coaxial cable feed line.  You can add 160 meters, any WARC band, and event 6 meters using the same concept. This antenna doesn't require an antenna transmatch (i.e. "tuner") and automatically band switches.  Tuning is a bit critical, since the antenna elements are fairly close together.  But, as an all around multiband HF antenna, the fan dipole works very well, especially for radio amateurs with limited space on their urban lots.

I've also used this design in an inverted vee configuration with good results. This antenna would make an excellent portable or emergency antenna.
