[amsat-bb] RHP LHP

Hi,I was thinking about getting the my eggbeater antenna,One thing I was hesitant about it is that it does just RHP.Is it that most Leo's use RHP?I have no idea what satellites have RHP or LHP,If anyone can tell me where I can find that info that would be helpful.Please excuse my ignorance.ThanksRich marzo7088@yahoo.com
