An V/U antenna for LEOs? Collinear's are not really Omni Directional



Hi Frank,

I would think that a Collinear would make a fairly poor antenna for
satellite work. 

You see a Collinear is NOT Omni  Directional. True in a terrestrial sense
it is, but its "gain" comes from redirecting radiation that would be headed
skyward towards the ground. Indeed, unless it is a steerable antenna, the
term "gain"  in an Omni generally means "not for satellite use".

What kind of coax are you using and how long?
