Done some experiments with the inventor wire harness tool. For the RG213 run from the patching plate to the room is roughly 10m, with a generous 5m left inside for internal routing this makes each run 15m. from our current RG213 cable stock we can make 3 of the RG213 links between the rack and the cable plate (given the existing cut in the RG213 we could only make 3 lengths anyway unless the total run length of the cables was less than 10m) and will need to buy an additional 30m of RG213 or similar. cable rg213 test

Some more rough lengths according to the cad diagram (need to check the size of loops). these values have been rounded slightly but haven't had any margin for excess factored in

Triband 12m 868 11m FM 11m Diplexer 10m HF 9m 70cm 3m (from diplexer)

This gives roughly 56m of Ultraflex 7. ML&S sell a 75m length for £89.10

here are the current cable paths cable test

These lengths are now out of date due to #44 and will need recalculating when more info is known
