The antenna will be free from obstructions, sticking out below a concrete support beam. That was my problem, the customer wanted to mount the 'Mast - mounted' antenna pointed upwards. They would then radiate right into the support beam. I alway try to put the omni's right out in the middle with out obstructions and not againt a wall, that is what a patch is for? Correct? Thanks again Tim Montag, 19.

If the pole were non-metalic then no problem. jack kwyjitim wrote: > Hello, > > I have a question regarding Antenna orinentation.
