Re: [SOCALWUG] Antenna Orientation

[adtt]

Thanks Jack. 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,

No problem with the polarization however if in pointing the "mast" omni
downward,
it "overlaps" the metal pole then the omnidirectiional radiation pattern is
going to have
a "null" in the direction towards the pole. If the pole were non-metalic then no
problem.
