Magnus, If you replace your RG-58 with RG-6 TV coax, your loss issues will disappear. The difference in impedance (75 ohms instead of 50) is not enough to cause problems. Adapters to the pre-fitted F connectors are readily available. And it's not expensive. Regards, Peter Magnus Danielson wrote:

[3]http://www.prc68.com/I/Ant.shtml#SBant It would be a little bit of a challenge... I think I have some 4-5 meter of additional height, the tiling is slippery and then antenna rig is kind of heavy, so it is not one of those things you do alone. At least I don't do it alone... I'm not a well trained radio amateur and the rooftop is not very well suited for elaborate exercises... I sure would like to have things like safety-line when working up there. I don't feel that safe up there. I don't know what it costs in Sweden, but in the US one can hire roofers or antenna installers to do such things, and they have the equipment. How did the TV mast get on the roof? A professional TV mast rigger did the job. I had a look at it again... and I'd say it is more like 3 meters up from the chimney, but it is still 4 m up from the roof at the chimney so it is a bit hard to get to. Anyway, the repositioned antenna now makes the borrowed Ashtech Z-12 lock up at L1 and L2 for sufficient amount of sats, but the S/N is lowish, which I think I will blame on my RG-58, not too professionally done coax work... could TDR it thought. Hmm... why didn't I think of that?
