If you need a simple, efficient multiband HF antenna, please trye the classic HF "Doublet Antenna." In this well-made video, "One Time Pad" takes us step-by-step through the design, construction, testing, and use phases of this useful, easily built antenna. Here are some suggestions from "One Time Pad": ulti –strand Flexweave) Ladder line/Open wire/Ribbon (I used 300Ω ribbon because its neater) x3 eye bolts with associated nuts as washers x1 straight wastewater pipe connector x2 access plugs for above wastewater pipe connector x2 wing nuts and bolts x2 Dog bone Isolators (to isolate end of each antenna leg) x1 spool Rosin core solder (i.e. solder with embedded flux) Cable ties Heat shrink tubing Mast Components: You will need to determine your mast location in advance. You will also need to determine

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.

Thanks to Adrian ("One Time Pad") for this excellent video tutorial on how to design and build a doublet antenna.  If you have doubts about your ability to make or erect this antenna, please ask for help from your local amateur radio club.  The project will go much safer and quicker with the help of friends. Adrian has supplied a full list of components and materials for this basic HF antenna: "Antenna Components: Copper wire for radiating element (I used multi –strand Flexweave) Ladder line/Open wire/Ribbon (I used 300Ω ribbon because its neater) x3 eye bolts with associated nuts as washers x1 straight wastewater pipe connector x2 access plugs for above wastewater pipe connector x2 wing nuts and bolts x2 Dog bone Isolators (to isolate end of each antenna leg) x1 spool Rosin core solder (i.e. solder with embedded flux) Cable
