A short answer, as high as possible, and as far from the house and power lines as possible. Last month, I've finally put up a Windom and the big goal was to reduce the noises that I get from the house and the power lines. What's nice about being below 30MHz is that you can run longer runs of coax without much loss. I put that Windom 60ft away from the house and power lines here, and what a world of difference it is to finally hear tough catches. Hope that helps.
The best two statements of advice that I've ever gotten are from my brother-in-law in the early 1990's. 1st one, when I bought a used '89 Olds Cutless, my bro-in-law said, "Congratulations!!! You've just bought a deficit!". The other, was on a work environment, " No matter where you go, it's going to be f***'ed -up!". No truer words have been spoken.

It still pays to use better coax if you can. 27Mc is close enough to the typical 30Mc db loss figures to be considered the same, 9913, lmr400, and even cable tv coax would do better than most rg8 and rg58. Better coax helps out on tx too, if all you have is 12w of ssb power from your cb, better coax will help get more of those 12w out the pipe.
