At Wimbledon club's 9 day summer camp GX3WIM @ Reigate hill this is what I did.

SITE LAYOUT as used most years.

narrow farmer's lane =======================================================================
Most of the caravans/campers & tents are powered up with 2 long ring cables runs. The main one was an electric start 7kW diesel running on cheap farmer's pink fuel, & I provided my 2.3.-3kW (modified) Madusa petrol generator as backup. I also used a 800W 2 stroke & a small 500W Honda, just for my station, if the big genny was not run during the day. (QRO still run)

As you can see with such a busy site some RF operating order has to be imposed, & it is done by being in possession of the "club logbook for that band", giving you permission to operate on it.
