HB: use man_made=tower instead of man_made=communications_dish ?
Glen: we should use man_made = tower as that proposal seems more fleshed out. I also added communications_transponder:service = satellite - A bit generic but better than nothing - At least we know it isn't GSM, etc.
RP: i think tower is good for now. these have all been round the block a few times, and will likely change again anyway - i can see several being consolidated
