Hello,
I am curious if the M2 egg beaters w/mast mount preamps would allow me to use the current satellites, including AO-7?

Sure. I have same working.

Just about any 2-meter antenna will work, when the satellite is over head. I have even worked ISS with a Rubber duck and a VX5R. (2-meter voice **).
The duration of your access window and quality of signal is determined by antenna GAIN. So to get your feet wet, use any antenna you can find, Zero dBd or better. Then if you find you like satellites and you want longer access windows and better signal quality, just add more antenna GAIN. Perfect conditions do not happen very often for low gain systems.
good luck.

** ISS rubber duck Conditions were perfect!!!! 80+ degree over head pass. Distance to ISS 300 miles (for a few seconds) Valery Korzun knew my call. Valery was on the air, 4 hours after his bed time, so there were few stations calling.

Hi Jeremy,
You can work all of the current mode B or J satellites using omni antennas. A good mast-mount preamp is necessary to be able to receive on 435 MHz like FO-29 or AO-51 but on 2 meters it is generally not needed which would include AO-7.
This past field day, Joe, KM1P and I made contacts on AO-07, FO-29, SO-50, VO-52, SO-67, HO-68 in FM mode and HO-68 in linear mode operating only a few hours on Sunday morning using omni antennas. We used an EZ-Lindenblad on 2m mounted at 6 feet with no preamp and a Parasitic Lindenblad on 70cm mounted at 10 feet with an SP-7000 preamp. (for antenna info see QST Aug 2007 and Feb 2010.)
I have made contacts down to less than 1 degree of elevation when conditions are good with just omni antennas.
Give it a try!
