I have one of these antennas. It works very well. Turns with an ordinary TV antenna rotor and I have worked the UK on many occasions. I was using a vertical (A-99 with an antenna tuner) and this is light years better. For people on a budget like I am this is a nice antenna to get you out on 10 meters and it is easy to assemble. Yes you can make your own but for the cost of materials it was so close I chose to buy one. Glad I did. If you follow the instructions it will get you pretty close. All I had to do was lengthen it about a quarter inch and my SWR was 1.2 across the tech section of 10 meters. On the antenna tester at 29 mhz it was still under 1.5. You can't beat that. You can see mine up on my QRZ page. Right now it is at 30 feet. Planning on raising it to at least 40 or 50 feet in the spring. Ran out of time before winter was coming.
