Spiderbeam 20-15-10m portable
The "Spiderbeam" is a light weight beam which is ideally suited for portable operations. Due to the construction with light glass fibre tubes and special antenna wire the antenna can be packed down to a transport length of only 120cm. With only 9kg weight is is well suited for dx-peditions.
The spiderbeam consists of three yagis on one boom. 3 elements for 20m, 3 elements for 15m and 4 element on 10m. This results in a gain of up to 9 dBD over real ground. Due to the light construction a small aluminum telescopic mast is suffcient.
The Spiderbeam is a kit, it has to be assembled before first use. At first the wire elements with the guy lines have to assembled. Even if the assembly has become much easier you should do this at home and not in the DX spot... The setup itself takes about 45 minutes. Due to the use of special antenna wire and high quality Kevlar guy lines a high stability and reproduceability is achieved. The feed is done with one common balun, only one feed line required.
