Matthew, You mentioned Time Server..is this your only GPS or do you have other more accurate timing requirements? Unless you are working on nanosecond type accuracy, I don't see that mounting your antenna on the metal roof is going to cause you any practical problems. If all you are interested in is taking time from your GPS over Ethernet using NTP, then all will work fine.

Can you mount it on a pole at the end of the > garden? I can, but the end of the garden is some 50 metres from the house, which brings back my concern of excessive cable lengths. We're in a bit of a weird situation - it's a rural location, but there are sheds, water tanks and all sorts dotted around and cables can only really be run along (steel) fences as vehicular access is required all around. (Think of a farm and you wouldn't be far off.) I had thought about putting the time server in the big shed and running an underground Ethernet cable (this is a fairly reasonable proposition) until the reflection issue came up - the shed (also steel) has a North to South roof, so the problem would be even worse.
