My main target is build an effective contest station for SOAB activities. During a long period a lot of different kind of antenna solution has been experimented. |

| A good hamshack is one of the base thing in long contests. During summer 2001 we finished a hamshack reparation project which is designed espicially to contesting. |

Even we don't have so much land or forrest to put up a lot of masts, we erected a fullrotating 36m steelmast to support main antennas(now there is Al-pipe at the top of mast holding 4th tribander, so total length is 41m). I have tested stacked monobanders for 5/5 for 15m and 4/4 for 20m, but because lack of enough vertical space, I noticed some coupling problems. Now I have make a compromise and powered main tower with 4 homemade tribanders and 3-el 40m fullsizer monoband yagi.

| This construction is quite similar than OH1JT & Co. has made in OH0Z. Thanks for OH1JT for all supporting information and help. | ![]() |

| I have also fixed mast for second direction antennas. This is next project target. There will be two stacked tribander for second direction. | ||||
| Next summer there will be plans to erect one and hopefully last steelmast for second radio. This mast will hold a couple of tribanders at fixed directions. Overall length will be abt. 30m. Some discussion with our neighbours is on the way because I have to borrow their land. | ||||
| For low bands I'm going to build an vertical antenna, which is quarter wave length at 80m and top-loaded at 160m. All material is ready. Only a lot of work is needed. This project is timed to winter 2001. Before that I'll use propably wire verticals and dipoles on low bands. | ||||
