I've always enjoyed "classic" antennas for their simplicity, efficiency, and low cost.  One of my favorites is the HF Doublet, which can be designed to cover all amateur radio frequencies between 3.500 MHz (80 meters) and 29.000 MHz (10 meters). 

In this enjoyable and detailed presentation, Adrian documents his construction of a doublet HF antenna from start to finish.  By using an antenna transmatch (i.e. "tuner"), a 1:4 current balun, and twin feeders (ladder line, tv window line, or homebrewed 600 ohm feed line), you can use Adrian's creation to cover several amateur HF radio bands--all this with one antenna.  Give this "old timer" antenna a try--you won't be disappointed.
