Physically, you would need the antenna height above ground level, direction, possibly which leg it is on and so on.

In the Netherlands we are facing the same problem with our GSM antenna’s.
Our country has the highest density of mapped GSM antenna’s (currently over 11.000) and you should see the worldwide mapping of the GSM 900 frequency:


We are using two solutions for mapping multiple antenna’s on one post:

Use technology=GSM 900;GSM 1800;UMTS
Together with

technology:1=GSM 900
technology:2=GSM 1800

An example of this last style is here:

Try to avoid using man_made=tower for structures that are definitely NOT a tower. And use mast:type instead of tower:type.
In an upcoming change of the carto style for the standard rendering, all man_made=tower will be shown and this will lead to an overflow of towers on the base map if you are using the wrong tagging. See my earlier post.
