Thanks so much for replying so fast.
The distance is about 500-600m as the crow flies. There's a map here

I want to get from the office to multimedia. The repeaters I thought would maintain line of sight by going from the office to the gym to the clinic then to fishman. Then either direct to multimedia or via arts and crafts. Is there no way I can repeat that many times?
Unfortunately when I say a lot of trees it is quite a large amount. There's one dense foresty patch and then some sparsely placed once along the road. The only way I can think of getting line of sight is to put an antenna at the top of the climbing tower. If I use a Yagi antenna then presumably I need one at both ends and the positioning needs to be quite precise? Do you know of any websites / books that have guides to setting up such a link?
Thanks again,
Ben
