or I have to improvise?  The rode NT-1A is too heavy for my stand besides long arm would be needed anyway
so hanging it up at the ceiling looks like a good idea. Can buy such hangers?  I hope mike will not sound different when upside down?
thanks

I haven't heard of anything such as a "ceiling hanger" for a mic, not to say that there isn't something like that developed. 

I have used (and continue to use) "heavy" mics on a boom arm, I just weigh down the mic stand to off-set the tipping.  

Many here have come up with a lot of ingenious ideas to make it work. Such as the weights from a "weight lifting set" concrete blocks, etc.

If you come up with a "ceiling hanger" post your findings here.

I've used these: flange   --mounted directly to the ceiling with a boom arm.

If you google microphone flange you'll come up with all kinds of cool stuff.

Get one of these, and maybe one of these. $12 and you're in business. You could also attach a short (6" to 3') mic stand or boom for greater flexibility.

unless it's a tube mic (which you're saying it's not) then there won't be any difference in the sound between hanging it upside down verses right side up.

tube mics or any mic which have high heat dissipation in them will sound different depending on the orientation.  some tube mics it is recommended to hang them upside down in order to keep the heat from rising to the diaphram. 

oh, so it's called flange...thanks guys I'll get it, in my studio I have long desk and regular stand won't do unless I'd put some concrete brick on the bottom, but I don't want to.
