My FM-antennas

Here a few photos of my antennas in Naantali. There are two little towers, nothing special.

Tower 1 (rotator)
- 8-element Triax yagi, vertical
- Körner 15.11, horizontal
- 2 x Triax preamps and rotator

Tower 2 (manual direction)
- 8-element Triax yagi with Triax-preamp
- 72 mhz dipole for OIRT

Tower 1 is about 4-5 meter high. The highest 2 meters of it is plastic. That's because the vertical antenna is connected directly to the mast. In this way the distance between V and H can be minimal (or could be installed even to the same boom).
Everything in tower 1 is painted black, so it is more invisible for neighbors.

A few years ago I tried stacking two vertical Triax 8-el. yagis with Triax-combiner but never succeeded. All got weaken for some reason (similar antennas, similar coax-feeds). I am not clever enough to build combiner myself.
