Need a little help. First I'd like to thank everyone for your answers to my question concerning ISS beacon.

I am all set to add L band to my station using my IC910 including Rohn 25 folder over tower to be mounted to the side of my house.  While I'm at it I wonder if it would make sense to add S band as well, if so, should I add transmitting as well as receiving capabilitie?  Should I use a two meter or a 70 cm radio knowing that two meter would provide less loss?  Any thoughts on this would be appreciated & most likley I will have further questions as I get into this project.

Thanks for any input. Jack WA1ZDV
