I am not going to be able to stack the antennas. They Would be about 25-40 feet apart horizantal. I guess what I need is 2 bandpass filters. I think thats what I am looking for. Now the big question. Can I build them? And where would I find the information? If I can't build them, where would be an inexspensive place to buy them? I don't know of any Elmers in my area that know about bandpass filters, or one that would take the time to help. Thats why I am here. Thanks, Kevin Kc7hgn
