We have built the towers and the antennas together,
each of us bringing his skills to the undertaking.

Special thanks go to “Finnish Antenna LTD” and its two designers, OH2HE and OH1JT.
All antennas on the 62m rotatable mast are their design and they made us go for the
JP-2000 tribanders (3 el on 20 and 15, 4el on 10) and have five of them
stacked at roughly 9 meter intervals from the top down. The uppermost
JP-2000 at 62m has its own rotor and can be rotated independently. 

Thus the stack can be controlled from the operating table such that
it is a full 5-stack, a 4-stack with the uppermost disconnected or the uppermost on its own
rotor fed singularly. On 40 we stack 3 of their 2 element compact beams.

We use compact beams in order to have them rotate freely under the 3 sets of guy-wires.
OH5KS actually made models of 9 different alternative configurations
before we settled for the present solution.

OH5LF designed the rotator system for the whole tower.
Without him beams would probably still stay fixed in one direction.

Our second 42m rotatable tower is the creation by the “antenna & tower grand old man in Finland” OH8QD. It has 6 element monobanders on 10 and 15, a 4 over 4 stack on 20, a 3el full sized on 40 and a recently added extra small tribander on its own rotor at the top of the tower.

Our location sits on a granite (rapakivi) bedrock and thus ground conductivity is very poor. Therefore, on the low bands (80 & 160) we have, through experience, found that the only competitive antennas are full-sized wire-loops. OH5XT set out to design the loops and we are particularly impressed with the performance of the two reversible double-loops for 80. Also the two single loops for 160 work very well. We particularly note the low noise-level using loops.

Our ideology is that operators bring their own radios and other equipment to the joint
contest station. From the photos included on this homepage you can see that several
of the leading brands of amateur radio equipment are present.

Computers have been donated to us, the courtesy of the OH5Z-club. We have 4-5 computers networked. They can also be hooked to internet when permissible. OH5CX is our data person, taking care of programming, networking and RF-elimination.

All stations are located in the two rooms of the old hen-house. In multi-single class we
usually have two full-fledged stations in each room.

We have found out, that OH5Z can never be completely finished on time before a contest.
Also we have found out, that generally a station can never be perfect, there is continuous development, up-grading and streamlining going on as technology is under continuous change.

We welcome new suggestions from anyone reading this page!
