My station is still very experimental, and is growing continously. The current status:

Rotators are Yaesu / Kenpro G-1000 (AZ) and Emotator EV-700 (EL, gear broken). The mast consists of 3 sections of 200x200 mm V2A, 150x150 mm Al and 120x120 mm Al and is integrated in the upper floor of the house. All parts of the antenna system can be maintained from the roof by a single person. The small antenna below is for my WLAN point-to-point link.
Cables between antennas, combiners
and preamps are H2000. The bands above 1 GHz have a separate RX cable (AIRCELL-7).
There are several AIRCELL-7
spare cables; I also have DC power 26 V / 100 A and Ethernet on the mast for
future projects.
Further improvements are planned:
I found out that the ECOFLEX-15 cables I have installed are widely out of specification, and show attenuation values on 1296 MHz which are not better than ECOFLEX-10. They were bought new! I cannot replace them easily as they are installed in a protective tube so it will need some time to improve the situation. Very bad!
Measured attenuation for installed 30 m AIRCELL-7, 30 m ECOFLEX-10 and 30 m ECOFLEX-15. All cables measured with Agilent HP8712C VNA as two 15 m sections looped through at the mast top.
