ok well i have answers and more questions
i have a 800Mhz duckie antennae and a stock duckie and an aerial one
Q1: would the stock duckie give better lowfreq response than the 800Mhz duckie? this is what i use when i drive around
Both antennas would basically work very poorly at low freq - the 800 Mhz duckie is not tuned for 40 mhz or so, and neither is the stock duckie. A good mobile antenna will do better, however you should keep in mind that it's simply not possible for one antenna to do it all well - there will be some compromises. This is probably a better topic for the antennas forum.

i also live in a house with other houses around and the aerial antennae is one from Radio shack it can also be a ham antenna but it looks like an upside down christmas tree with some other radials around it about 2' diameter x 3 feet tall i have other questions about its increased performacve if i raise it on a pole attached to soffit??
Again this is a question best put on the antennas forum, but yes, it would work far better getting it up off the ground, and in the air. The higher in frequency you go, the more the kind of coaxial cable you use to connect it makes a big difference - using cheap cable will lose much of your desired signal, particularly at 800 mhz.

i ask about the milair cause i read about space ranging? the way different scanner scan in steps what does ARTCC mean what they do? also the copter excereise here a year ago was saving people from the roofstops i luckily wasnt so then i was wandering what the air chatter and search and rescue soudned like
two weeks later i got my first scanner
thanks again man
peace
I have no idea what you're talking about re 'space ranging'. However, different freq ranges do indeed have different steps, and that should be laid out in the manual.
Basically, an ARTCC controls and directs flights above and between certain altitudes; keeping them apart a safe distance, giving them vectors and other traffic related to getting an aircraft through their airspace. Mil flights use these freqs for the same thing, as well as keeping aware of what civilian traffic might be in their general vicinity.
We have a number of very good folk over on the Antennas forum; since you seem to have numerous questions on the topic, I'd start there. Take your time, there's a great deal to learn. 73s Mike
