hello

hello guys i want some help about receiving weather satellite image from space ,i bought yesterday an antenna from somebody 1/4 lambda omnidirectional very powerfull it says from 108-137 mhz ,so can somebody tell if this is good for all satellite weather to receive i mean like meteor-m n2 the new one that has been launched or other satellites like noaa ?

What type of antenna is it - by 1/4 wave lambda do you mean a 1/4 wave ground plane antenna?

For satellites you generally want a proper satellite antenna, like a Turnstile or QFH antenna.

A 1/4 wave groundplane might work okay but you'll probably find that the signal fades in and out, or only gets signal when the satellite is low on the horizon.

Sorry not sure what a "1/4 wave lamba type" is, I assume it's a 1/4 wave ground plane though, something like this: http://upload.wikimedia.org/wikipedia/c ... _vhf_3.jpg.

Yes you will probably get a signal with this antenna, but it is not a proper satellite antenna so the signal may fade in or out as the satellites polarisation changes. If you get a very strong signal it might not matter though.
