Over the weekend I decided to try and connect to the ISS's repeater at 437.80000 while it passed overhead. I was able to make contact with other hams several states away. Pretty cool, I'm using a home built vertical dipole and was able to connect only for a few minutes. I might try mounting the dipole vertically and see what happens.

I read where there are four vertically mounted 2m/70cm antennas in use on the ISS. I would assume that I would want to keep my dipole vertical to have the same polarization. From what I have read an adjustable circularly polarized crossed-Yagi antenna is the best antenna to use.

Hey, That was a neat experience Joe ! --- talking thru the ISS :giggle:

Yes, you want to use circular polarization for satellites - it can be anyone's guess just what the signals will be doing by the time they get back to you.
Remember your radio theory ? the ionospheric effects of Ordinary and Extraordinary radio waves ? No? (I am kidding :giggle:)--- its best to just stick with circular.


Now think, if only there were geo-stat ham sats for our hemisphere ..................
