I was thinking about a 4-way stack of quagis since they're easy and cheap to build. Thoughts on these? I have an SDR play for reception. Also have a LNA. Haven't found any filters yet. Recommendations welcome, otherwise I'll get around to googling. What to do about feedline? 1/2 hardline losses are quite high. I could possibly get the feedline down to 15 ft if the antennas can fit in the attic (i know, not ideal). I'm not-yet concerned with TX. I want to verify that there is some activity around before going full-bore into this band. Thanks for any guidance.
