My Skypper beam antena

After last winter. I had to fix my Skypper beam antenna. Frost destroyed the links tensioning design. I changed the rod. They are now 4 feet long. Were strained, each up to 3 meters. Below is a photo of my design, after such revision.

Director is a half wave section and it is adjusted electrically. I used a 1:1 balun 2mm copper wire wound on a ferrite ring.

I am very pleased with the improved design and operation of the antenna. The antenna is connected to the transceiver using coaxial cable H-155. Spider is tuned to the frequency of 27.555 MHz. SWR at this frequency is 1.1. I'm working on four-element Skypper antenna characteristics. If I can get a satisfactory result. Included here the results of my work.

Active supports microprocessor control powered by SP8NTH.

and the program Ham Radio Deluxe Rotor.

Feel free to comment on my blog located on this website My Skypper beam. As well as providing assistance in the construction of other colleagues.
