There is a section in the rules that require the coverage of paint on the

Any of my companies coax that runs outsidethe painted tower structural parts must be painted. If we run the coax inside the tower structure we don't have to paint the coax.

Do you suppose it's the same board as in the TRN1192A? Probably not. The

It's a good antenna, but it is long, heavy, and rather expensive.
When you are shopping for a 900Mhz antenna, you really need to look at what you want the antenna to do. The particular antenna that you picked out would play superbly to the horizon, but would overshoot the area just below it if
