Sirs:

I am a programmer and electrician, but not a radio person! I am
sending an experimental balloon to over 100,000 ft. I have purchased
two 900MHz RF Aerocomm ConnexLink Radios. The radios have a power of
1000 m.a., which states it will transmit and receive up to 20 miles
line of sight. I do realize that this is probably under ideal
circumstances and will not likely be the case when I actually deploy.
I would be interested in purchasing some antennas which would somehow
increase the range. What sort of characteristics make up a good
antenna for what I want to do? It is possible that someone could find
me one that would work with my project? Also, anything you might
contribute concerning radio transmission would be very much
appreciated.
Money is no object for this experiment, so any ideas you have are very
much welcome.

Thanks,
Brett


Hi Brett .

Is it possible that your radio power level is 1,000 m.w. rather than 1000
m.a.?

I think this 'antenna' problem can be easily/inexpensively solved. if the
location of the balloon is known.

It most certainly is 1000 m.A.! I must have been quite exhausted when
I wrote that.

The location of the balloon is not 'known'. I was hoping that you
would not have to point the antenna in the general direction. Can you
get an omnidirectional antenna?
Thanks,
Brett

I must be cursed:
Yes, the power output is 1000 milliwatts.
