A fascinating video from Tim (2E0TWG) on how to squeeze a good performing multiband doublet antenna into a restricted garden space.  In Tim's video, we see how careful planning can set up an efficient dipole antenna in a space measuring 30 ft X 30 ft (9.146 m X 9.146 m).  Tim's antenna is only 44 ft (13.41 m) long, yet it performs well on several amateur radio HF bands.  Perhaps Tim's project can be used in your yard.  It's worth a try.  Remember the old saying:  "A compromise antenna is better than no antenna at all."

If you want a little more "punch" from your 20 meter vertical antenna, why not build Bob's (VK5FO) end-fire phased array of 2 X 1/4 wave length elevated ground plane antennas? Bob walks us through the general theory, construction, and alignment of this directional antenna which can give about 3 dBi gain over a single 20 meter monopole vertical antenna. Most of the materials for this phased vertical array can be obtained from your local building supply outlet, neighborhood hardware store, or through a few online vendors. A basic, simple, and fairly inexpensive way to get some gain from a vertical antenna.

Here's a simple and elegant solution to keeping common mode currents off your coaxial cable feed line. According to Australian radio amateur Peter Parker (VK3YE), this basic choke "balun" only uses a few materials: 7 meters/22.96 feet of RG-58 coaxial cable. 75mm/2.95 inches diameter piece of PVC tubing. A few connectors. Be sure to weatherproof the assembly.

Although some of my amateur radio friends will call KD0RVY's "2m Ladder Line J Pole" a "Slim Jim", the basic idea given in this well-done video is sound, doable, and extremely useful for portable, emergency, and field operations. KD0RVY takes you step-by-step through the design, construction, and testing phases of this handy, lightweight, and inexpensive antenna. According to KD0RVY, here's a list of the materials needed for this antenna: 60 to 61 inches/152.40 to 154.94 cm of 450 ohm ladder line. A MFJ Ladder Line board with BNC connector. RG-58 or RG-8X coaxial cable. RG-58 or RG-8X coaxial cable with BNC connectors at both ends. BNC Female to SMA Connector. A 2 meter HT. KD0RVY says the SWR for this 2 meter antenna is excellent:  144.000 MHz (1.2:1) and 148.000 MHz (2.0:1). For the latest Amateur/Ham Ra
