Great portable HF multiband antenna w/o counterpoise  Time owned: more than 12 months
Used with a portable radio and with a good tuner, I've found the DK9SQ vertical 20m loop to be a great portable HF multiband antenna without the need for any counterpoise. The strength of the design is in the ingenious ways in which the poles interconnect with the balun box to make a strong yet light supporting cross, how the wire is held by the telescopic poles, and how it connects to complete the loop. The use of parallel electric cable to feed one of its horizontal angles from the balun, permits the latter to be at the centre of the loop, thus permitting its box to act as its structural cornerstone and still have the feeding point at one of the side angles for good elevation and directionality. I did find the actual balun to be very flimsy and not in accordance with the qualty of the rest of the antenna, but this was easy to solve by replacing it with a 4:1 home-brew toroidal chore balun. With the Elecraft KX3, and using its internal ATU, the loop is readily tuned to 1:1 SWR in all HF bands from 80m to 10m. When deployed portable in the outdoors it also makes for a great curious-attractor and conversation piece... 73, de Jose VA3PCJ.
